You are running up against the last case I mentioned, namely: > 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. Ie., because PythonHandler is for '/var/www', only that directory is added to the Python module search path, not the "python" subdirectory. Change the Directory directive to "var/www/python" and it should work. Alternatively, move "steve" into '/var/www'. Ie., a module import from a handler does not implicitly look in the same directory as the handler first like when using Python normally.
