If I understand correctly, you are running makepy (or genpy) from within
the packaged program?

If this is so, there are 2 problems:
- where will the generated files be created, and how can you determine
  this directory,
- how do you import these files.

For the first problem, you should read the win32all code, and experiment
with the exe.
Foe the second problem, IIRC, you don't need a custom importer
(probably). The exe-file still can import from the file system, just add
the directory to sys.path.
