I don't know what web server you are running or which version, but in a
previous job, when I routinely built the latest Apache 1.3 with some
bells and whistles, I recall there being some issues caused by mm shared
memory lib support being compiled in.  I was using mod_perl and mod_php
at the time, and not mod_python.  May not be relevant, since one problem
I recall led to the server not even starting.

One tip: 'os.environ' is a dictionary of environment variables for the
current script.  You can use this dictionary to initialize your script
to precisely the same environment your interactive shell enjoys, e.g.:

---------------------------------------------------------
import os
#-- Insert new path at front of LD_LIBRARY_PATH env var
os.environ['LD_LIBRARY_PATH'] =
  '/usr/local/freetds/lib:%s' % (os.environ['LD_LIBRARY_PATH'])
#-- Initialize SYBASE env var
os.environ['SYBASE'] = '/usr/local/freetds'
#-- etc. etc. etc.
---------------------------------------------------------

This might prevent a slip between the shell and the script ;-)
