And there be the real problem. Either that version of Python hasn't
got the md5 module installed, or you are running PHP on the same
server and it is loading the mhash.so PHP module which has shown in
the past to conflict in bad ways with mod_python.

Thus, check if from command line Python you can import 'md5' module.
If that works, disable PHP on web server and see if problem goes away.
If it does, work out how to disable PHP mhash.so so it doesn't load.
