[mod_python] frustrating problem importing packages with mod_python

Where is the "steve" package located in relation to the directory
containing the handler? What is your Python sys.path set to? Are
you overriding "PythonPath" directive? Are you using a ".htaccess"
file to enable use of publisher or the main Apache configuration
file? If the latter, have you used the "Directory" directive or
the "Location" directive to surround the mod_python definitions?

Try and answer these questions. Also post what the part of your
Apache configuration looks like where you enable use of publisher
for mod_python.

One warning, if you use "Location" in the Apache configuration
instead of "Directory", mod_python will not be able to add to the
Python module search path the physical directory for which the
PythonHandler directive is defined, ie., where your handler
potentially resides. As such, if your "steve" package is in a
subdirectory of your handler it will not be able to find it.
Further, even if "Directory" is used, if both the handler and
the "steve" package are in a subdirectory of the directory for
which PythonHandler is defined, it will not find "steve" as only
the top most PythonHandler directory is added to the module search
path.

Anyway, explain better how your directories are laid out etc
and then we might be able to be more specific.
