Run an interactive Python session and try:

grumpy:~ grahamd$ python
Python 2.3.5 (#1, Mar 20 2005, 20:38:20)
[GCC 3.3 20030304 (Apple Computer, Inc. build 1809)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
 >>> import anydbm
 >>> db = anydbm.open("/tmp/mp_sess_test.dbm",'c')

If that works, try the same thing in a really simple mod_python handler
independent of Session class. Ie.,

from mod_python import apache
import anydbm

def handler(req):
     req.content_type = 'text/plain'
     db = anydbm.open("/tmp/mp_sess_test.dbm",'c')
     req.write('test ok')
     return apache.OK

If it works outside of mod_python and not in mod_python, may be some
problem to do with a mixing of wrong versions of shared libraries.

If it doesn't work outside of mod_python either, make sure permissions
on "/tmp" directory look correct, or try creating it in a different  
that you own.

Time for me to sleep. Will see how you go in the morning.
