If you are specifying:

   PythonHandler mod_python.servlet

or:

   PythonHandler servlet

if you put the mpservlets code in your handler directory, then you are.

This is because the PythonHandler directive uses "apache.import_module 
()".

All it then takes to cause problems is for you to use:

   import mod_python.servlet
   from mod_python import servlet

or:

   import servlet

depending on whether mpservlets installed centrally or in handler  
directory.

If this is the case, you might solve the problem by using  
"apache.import_module()"
to import "mod_python.servlet" etc.
