multiple compile-install phases

Hi list,

I've encountered a few cases where the build process
requires building and 
installing something and then using that to build something
else. Is there a 
standard way to do this?

I'D SAY - SPLIT THE PACKAGE IN TWO (OR HOW MANY PIECES THERE
ARE). SUCH 
PROCEDURE IMPLIES THAT THE PARTS ARE ALREADY WELL ISOLATED,
SO THE SPLIT 
SHOULD NOT BE THAT HARD TO DO. TRYING TO FORCE IT "IN
ONE GO" IS NOT TRIVIAL 
USUALLY, UNLESS WHAT YOU ARE TALKING ABOUT IS SOME BOOTSTRAP
PROCEDURE. 
HOWEVER IN THAT CASE THERE SHOULD BE A CERTAIN WAY OF
"PROPER BOOTSTRAPPING" 
FOR THE PACKAGE DESCRIBED IN ITS INSTALL DOCS.

Perhaps you could build the build tools and install them to
some
directory under the temporary build directory and use them
from there by
adding that directory to $PATH or by calling them with full
pathnames. 

Do the build tools in question need to be installed along
with the
desired end product, or are they nothing more than
integrated build
prerequisites?

Splitting the package is a good idea indeed.

If it is needed a bootstrapping , you could build a binary
version of
the necessary components of the package, that's what we do
with ghc and
many of the languages packages inside dev-lang.
