separate shared libraries or different Linux/Unix

Well I've done --enable-shared so that I can compile mod_python as a
shared object within apache.
Created /etc/ld.so.conf.d/python2.5.conf on a redhat system, and put /
opt/python/lib
and it works no probs.

Each to their own.  I have a hosted virtual server, and I would like
to get another one for another project.
I want as much built from source as I can manage so that I know what
is and what is not on the system.
zlib is compiled with --enable-shared in /opt/zlib-1.2.3 and I've
ldconfig -n /opt/zlib-1.2.3/lib

I'm compiling python from source, because the server is running redhat
5 which comes with python 2.4
To run trac you need python2.5
I'm running into a problem where zlib is not available even though
there is a copy in /usr/lib/ of the version I compiled.

In /usr/local/src/Python2.5.2 I'm doing:
./configure --enable-shared --prefix=/opt/python --with-zlib=/opt/
zlib-1.2.3
make
make install
When running the setuptools egg, it says zlib unavailable.

Back in the config.log of the Python2.5.2 source directory, it shows
that it's passed in, but in that file there is a --with-system-zlib
How do I get zlib available to python?

Cheers
