New sudo with Apple Update 10.4.9 break access to Fink libs

Howdy,

In case it's of interest to anyone:

I regularly install new OS X systems with Fink and a large
handful of perl 
modules from CPAN for my company's work environment. I
install some libraries 
and perl libs through Fink first, then I use CPAN to install
a bunch of other 
modules (we use the Apple-supplied perl, mod_perl and
apache).

Yesterday I started to perform another such install, and
CPAN just would not 
pickup the modules/libraries installed by fink. I was
stumped until I figured 
the only thing "different" from every pervious
install was the recent 10.4.9 
update.

I looked into it and sure enough, the latest update contains
a new version of 
sudo, which now sanitizes various environment variables
pertaining to perl. 
In this case, Fink is affected by the removal of $PERL5LIB.

I wrote some more details, including how to defeat this new
sudo "feature" and 
posted them here:

pples-mac-1049-update-breaks-cpan.html

I'm probably the last person to figure this out, but I
didn't see any other 
discussion about it on the list so I thought I'd share my
discovery, in case 
anyone else runs into the same problem.

Thanks!

fink-0.26.x and later have been modified to work around this
very 
problem, so we encourage people to upgrade.

It has been discussed on several Fink lists, fink-core,
fink-devel, and 
even once on fink-beginners, but apparently not on
fink-users.
See for example
<http://thread.gmane.org/gmane.os.apple.fink.
core/1408/focus=1417>
<http://thread.gmane.org/gmane.os.macosx.fink.devel/1
4250>

As Alexander explains, fink itself has been aware of this
for a while 
(as part of the preparation for 10.5) and has been fixed to
work with 
the new version of sudo, even before 10.4.9 came out.

For other perl programs, and also for bootstrapping older
fink versions, 
two workarounds were proposed: Besides what you have found,
namely 
running "sudo visudo" and adding

Defaults env_delete-="PERLLIB PERL5LIB PERL5OPT"

to /etc/sudoers, a less intrusive method was suggested,
namely using the 
command

  sudo env PERL5LIB=$PERL5LIB cpan

instead of simply "sudo cpan".
