[mod_python] wrong version?

2 versions of apache

just ./configure --with-apxs=/usr/local/apache28/bin/apxs

I did make install

And no, I don't understand the shared library issue.  Unfortunately I'm
pretty much a noob, since any previous apache haven't required any modules.

Thanks for all the help.  Let me know if you have any other ideas.
