I am doing this on a (old) Fedora Core 3 (x86_64). I am not a whizzkid
in compiling stuff so I apologize if this turns out to be a common or
obvious error.

Try reinstalling Python but this time ensure that when you run
configure for Python that you supply the option '--enable-shared'.
This will enable the generation of a shared library for Python, ie.,
libpython2.4.so instead of the libpython2.4.a. The x86_64 platforms
seems to only like linking against a shared library.
If after doing that mod_wsgi does compile, run the command:
ldd .libs/mod_wsgi.so
in the mod_wsgi source directory. This will generate a list of the
shared libraries that mod_wsgi.so requires. It should now list
libpython2.4.so. If it cannot find that library though, set the
environment variable LD_RUN_PATH as:
LD_RUN_PATH=/usr/local/lib/python2.4/config
export LD_RUN_PATH
Then run:
make clean
and:
make
again to rebuild mod_wsgi.
Setting LD_RUN_PATH is sometimes needed like this because
libpython2.4.so not installed in standard library path when doing own
build/install of Python like you have. Run 'ldd' command again to then
see if it finds libpython2.4.so.
If any problems, send 'ls -las' listing of contents of
/usr/local/lib/python2.4/config and .libs directory in mod_wsgi source
code and the output of the ldd command each time you run it.
The LD_RUN_PATH variable only needs to be set when you are building
mod_wsgi, doesn't have to be set when running Apache.
Even if works, appreciate you sending me those directory listings and
ldd output. Actually would be good if you can send them to me a copy
of what they look like before you trying rebuilding Python so I have a
before and after, then I can use it all as examples in some proper
documentation for this specific problem.
Thanks.

I got mod_wsgi working. I like it. Setup in apache config is simple. I
have only got it installed on my development machine. I have no
'scientific data'. But, it feels solid and quick. As I said earlier, I
am not a compiler whizzkid. So, here is what I did.
This is the output of ls -las /usr/local/lib/python2.4/config before
recompiling Python:

This is the output of ls -las of the .libs directory in the source of
mod_wsgi before recompiling Python:

Then I recompiled Python using --enable-shared. I also swithed
versions, because I downloaded Python 2.5. This was easy. I just did ./
configure --enable-shared, make and sudo make install. That's it.
However, when I ran python on the command line I got an error about
not finding a shared library. So, I did /sbin/ldconfig. Now Python 2.5
did run.
Next I went to the source directory of mod_wsgi. Did ./configure, make
and make install. It just worked!
This is the output of ls -las /usr/local/lib/python2.4/config AFTER
recompiling Python:

This is the output of ls -las of the .libs directory in the source of
mod_wsgi AFTER recompiling Python:

3104 -rwxrwxr-x 1 berry berry 3173332 Mar 26 23:32 mod_wsgi.so
Then I followed instructions for the integration of mod_wsgi with
Django and it worked perfectly!
Thanks very much for your help.

First off, the AFTER listing you gave for config directory was that
for Python 2.4 and not the Python 2.5 you said you ended up using. Can
you do the same for Python 2.5 config directory?
Second is that the final mod_wsgi.so file is over 3MB which suggests
it still didn't use a Python shared library but a static one. Thus
need to see what was in Python 2.5 config directory as above to verify
the --enable-shared did what I expected and generated a
libpython2.5.so.
Since Python 2.5 is not standard Python on your system, did you use
--with-python option to mod_wsgi configure script to tell it which
Python to use?
