Error importing modules with mod_python

[Aaron Scott]

I've installed mod_python, and everything seems to be working, but it
fails when I try to import another file into the file that's actually
producing the output. I have these lines at the top of index.py:

from mod_python import apache
from storylab import *

... and in the directory where index.py resides (/htdocs/python/), I
have a directory called "storylab". Inside that directory is
__init__.py. When I try to execute /htdocs/python/index.py, I get the
following error:

---

MOD_PYTHON ERROR

What am I doing wrong? Any insight would be greatly appreciated.

Thanks,
