Upgrade questions

Hello,

I'm trying, at long last, to upgrade my ports (including
Xorg) on my
clunk old 6.2-RELEASE system.  I know that I probably should
have done
this long long ago, but I have two things working against
me:  I'm lazy
and I'm ignorant.  In particular, although I have been using
FreeBSD
for years, I've never really messed with ports, except for
occasionally
building and adding one, every now and again, when I found
that I
needed something that wasn't already present on my system. 
So port
upgrading is kind of a mystery to me.  I've been reading
about how
to perform proper port upgrading, just now, and trying to
educate myself
about the process, but I confess that I'm still quite
ignorant.  So
please take pity on me and answer juat a few of my basic
questions.

First, a short while after I started up "make
index" in the /usr/ports
directory, I received these messages:

Generating INDEX-6 - please wait../usr/local/bin/python2.5:
not found
"Makefile", line 43: warning:
"/usr/local/bin/python2.5 -c "import sys; print
sys.version[:3]"" returned non-zero status

Could somebody please tell me... What do these messages
mean, and do I need
to worry about them?

OK, next question... The 20070519 note in the
/usr/ports/UPGRADING file
says "If your machine does NOT have any gstreamer ports
installed..."
OK, so excuse my ignorance, but how the bleep am I supposed
to know if
I have any gstreamer ports installed?  I don't even know
what a gstreamer
port is!

The 20070519 note in /usr/ports/UPGRADING then goes on to
say:

	... you can then just run:

	# portupgrade -a

but that upgrades _all_ my ports, doesn't it??  What do I do
if I'm not
prepared for that?  What do I do if I want to take this
process a step
at a time, and first just upgrade _only_ the Xorg stuff and
any other
ports that are dependant upon that stuff?  How can I do
_just_ that?

Lastly, the 20070519 note in /usr/ports/UPGRADING also
says:

	Make sure you have the x11/xorg meta-port installed.  If
you do not
	have this meta-port installed with X.Org 6.9, you will miss
out on
	a lot of the new X.Org 7.2 sub-ports.

I'm sorry, but these comments are entirely opaque to me. 
Can somebody
please lend a hand and explain what all this is actually
supposed to mean?
You know...  I mean to somebody like me who isn't steeped in
this stuff?

How exactly do I "Make sure you have the x11/xorg
meta-port installed"?
What are the exact commands necessary to do this and when,
during this
whole relatively convoluted upgrade process (and relative to
all of the
other commands shown in the 20070519 note), am I supposed to
execute the
(mystery) command(s) in question?  I mean do I need to this
this _before_
a try to upgrade from Xorg 6.9 to 7.2?  Or just after?

I'm very paranoid about this whole Xorg 6.9->7.2 upgrade
process and I'm
really afraid that... bacause I'm so ignorant... I'm going
to break things
really badly and in the end find myself stuck with an
unusable system.
So I'd really appreciate it if someone could just answer my
questions above
so that I can make sure that I'm approaching this whole
upgrade task properly.
Thanks.


Regards,
rfg


P.S.  OH!  One other thing... I just now updated my ports
tree... the first
and _only_ time I've ever done that in my life... using
"portsnap fetch"
and "portsnap extract" and then I wanted to see
what things I had installed
that might be worthy of upgrading, so I did:

   pkg_version -v

well, THAT didn't work out well at all.  I got a whole raft
of errors from
that which mostly looked a lot like this one:

xorg-6.9.0                          <   needs updating
(port has 7.3_1)
"Makefile", line 85: Could not find
/usr/ports/x11/xorg-clients/../../x11-servers/xorg-server/Ma
kefile.inc
"Makefile", line 92: Malformed conditional
(${X_WINDOW_SYSTEM:L} != xorg)
"Makefile", line 96: if-less endif
make: fatal errors encountered -- cannot continue


OK, so what is the proper solution to this?  Will the
"pkg_version -v"
command not even work _until_ I upgrade my Xorg stuff?? 
That doesn't
make a lot of sense.  I thought that "pkg_version
-v" was supposed to
tell you what needs upgrading, yes?  And this fundamental
tool doesn't
even work right until you have _already_ upgraded one
package, Xorg,
to the current level??  That sounds like a Catch-22 to me.

Not sure,although that port was just updated.

In any case, it's MUCH easier to use 'portsdb -F' to
download the latest
Index-6 file.

Good Question. 'pkg_info gstreamer-*' would be a good
start. There are
LOTS of gstreamer ports, so this could generate a lot of
output.

No, 'portupgrade -af' upgrades all of your ports.
'portupgrade -a'
updates all of your ports that are out of date...which is
the normal
default use of portupgrade, at least for me.

xorg was broken up into a whole raft of small ports for
different libs
and clients in place of the old libraries, servers, and
clients. The
xorg metaport is a single port that simply depends on all of
the ports
that make up the complete xorg distribution. By installing
that, you can
be sure that you have a full xorg installation.

> How exactly do I "Make sure you have the x11/xorg
meta-port installed"?

'pkg_info xorg-*'. Look for just 'xorg-VERSION' as there
are several ports
that are prefixed with 'xorg'. If you don't see it, after
upgrading
installed ports, 'portupgrade -N xorg' to install it.

You need to use pkgdb -Ff to clean up or database. Also,
pkg_version is
a fairly dumb tool. Using 'portversion -v' is both faster
and more
likely to run cleanly.

Unfortunately, I suspect your database is not too clean, so
you may have
a LOT of errors reported. Food luck!

Wow... quite a list.

Most of these questions are more related to the ports
infrastructure
than specifically x11.  You will get better response to
general ports
questions on portsfreebsd.org or questionsfreebsd.org than here.

Second, you'll get much better response if you send out
email for one
issue at a time.  And I'm afraid I think you're going to
have to learn
something along the way ;).  And as a result, you'll be less
afraid
of the whole process.

I'll respond to some of these questions, but a lot of them
are general
and can be addressed a number of different ways.

It sounds like you have a bit of a learning curve, and we
have no idea
how much you know or don't know.  It seems you picked a big
complicated beast with lots of twisty interactions to start
learning
with.  If you're patient and willing to experiment/learn,
you can do
it.  If not, perhaps try a binary install from 6.3 release
CDs.

I don't mean to scare you.  None of this is really rocket
science.
But there's lots of niggly details with the upgrade from
xorg 6.9 (I
assume) to the latest (changes to modular X.org build
infrastructure
and from /usr/X11R6 to /usr/local).

Having said that, I'll answer some of your questions
inline...

a few comments...
 - out of date or corrupt ports tree (cvsup or other tool to
update your ports tree)

 - corrupt ports installation (try 'pkg_info -g -x .')

 - corrupt /var/db/pkg database (ditto)

 - if you haven't customized your ports tree and
   it's up to date, try just fetching the index instead of
building it...
      (cd <your_ports_tree> ; make fetchindex
PORTSDIR=.)

pkg_info | grep gstreamer

You probably should be reading the handbook rather than
asking the x11
mailing list these kinds of basic questions.

Note I have no idea whether following the 20070519 note
verbatim is
guaranteed to work anymore now that the ports tree has
evolved.  Maybe
someone else knows if it is still an effective tool.

Yes... well it'll try to anyway.

Yes, it's possible to update incrementally, but I won't try
to
explain it in a sentence or two here.  Try it, and ask more
specific questions as you run into trouble.

One possibility to consider is to install fresh ports into a
chroot.
Consider also using packages (pkg-add -r or
portupgrade/portinstall -P
or -PP) to save time and complications with build-time
issues,
although that means you have to take ports that were built
the way the
packaging machine built them.

Another is to just pkg_delete your old xorg ports, then
install new
ones fresh.  You'll have to live without X while you do,
however
(well, in theory, you could start the old X, then delete its
packages
but keep running the old X until you get the new one started
- I've done
that before and tried running the new X with startx -- :1
leaving
the old one runing on :0).

There's about 50 other ways to skin this cat I'm afraid.

"Make sure you have the x11/xorg meta-port
installed".

What's a meta-port?  A port that really doesn't install
anything of
its own (at least not much, usually), but rather doing 'make
install'
in the port triggers it to go out and build/install a list
of other
ports recorded in its dependency lists (see the *DEPENDS
variables in
the Makefiles or run 'make pretty-print-build-depends-list
pretty-print-run-depends-list' or other ways).

You may then ask, "How do I tell if the xorg meta-port
is installed?"

If it was installed properly, this is one way...
pkg_info -O x11/xorg

Note that 'pkg_info -L -O x11/xorg' won't list contents
because, being
a meta-port, it doesn't actually install any files of its
own.

If your ports tree is really up to date, that file should
 a) not be there
 b) not be referenced (grep -r xorg-server.Makefile.inc
/usr/ports)


 > "Makefile", line 92: Malformed conditional
(${X_WINDOW_SYSTEM:L} != xorg)
 > "Makefile", line 96: if-less endif

That happens if a Makefile or included .mk file tries to
reference
$ and that var is undefined.  If you have a
ports
tree that matches the port tree from the 6.3 release (note:
not the
same as the latest ports tree as of today, the so-called
HEAD) then
there should be a line in ports/Mk/bsd.port.mk that has
'X_WINDOW_SYSTEM ?= xorg' which defines that variable.

It seems something is not right with your ports tree.  Why? 
I don't
know, but fixing that may alleviate lots of your other
problems.
