* 
* I'm using mod_python version 2.4.1 on a RedHat 6.2 machine,
* kernel 2.2.16 and Apache 1.3.12
* 
* The module was compiled with the following command:
* 
* apxs -c -I/usr/include/python1.5 -L/usr/lib/python1.5/config \
* -lpython1.5 -lpthread -lieee -lm -ldl mod_python.c

You probably want to link python in statically, I did something like

apxs -c -I/usr/include/python1.5 mod_python.c
/usr/lib/python1.5/config/libpython1.5.a -lpthread

* 
* 
* I'm including a complete list of module loads and a backtrace of the
* core dump.  This segfault does not occur if the LoadModule for
* mod_python are commented out, but does if only the AddModule is.
* 
* I hope this was somewhat helpful,

I assume that you are consistant in the threading (both python and mod_python are threaded or neither).


However something that I found was that trying to use a threaded python
in a chroot'ed environment didn't work. Threaded python worked okay
outside the chroot and a non-threaded python worked okay in th chroot.
