Does adding the following to the Apache config help:

    PythonPath "['/usr/local/apache2/htdocs/test']+sys.path"

Place it in the Directory directive.

This is not documented (probably should be especially for newbies as I
was!) but after a lot of headaches and experimenting it got my
implementation to work. It appears mod_python/python needs to be told
informed of every directory a python scripts frequent.

cheers
