There are various problems with module import in currently available  
versions
of mod_python. See:

   http://www.dscpl.com.au/articles/modpython-003.html

for further details.

Most of the issues will be addressed in mod_python 3.3.

There are two ways you can get around the problem. Not sure which is  
most
appropriate given your circumstances.

First is to use PythonPath directive to specify extra directories to  
search. This
is the same as setting PYTHON_PATH environment variable for command
line Python.

Second is to use the apache.import_module() function to import modules,
specifying a path argument of directories to search. Ie.,

   module = apache.import_module("name", path=['/some/path'])

Check the mod_python documentation.

Sorry for brief reply, in a rush.
