Define "don't work at all".

It sounds like you are trying to fight Python's module system instead of
working with it. In Python programs, you don't "run" other modules, you
import them, then call functions inside the module. You treat the modules
you write exactly the same as standard library modules.
As a general rule, you would never say:
Instead you would say:
The same rule applies for your modules. As a general rule, NEVER say:
(There are exceptions, but if you need to ask what they are, you're not
ready to learn them! *wink*)

Sounds like a horribly fragile, complicated and complex way of doing

Sounds like you're trying to implement plugins. For that, __import__() is
your friend. execfile() is *not* your friend -- you might think it is,
but don't listen to it. It's like one of those guys who calls you "buddy"
and talks you into doing things that you regret the next day. Trust me,
use execfile() and you'll end up waking up naked in an alleyway in Vegas
married to someone called Lula-Mae, with no memory of the last three days
and a tattoo of Paris Hilton on your butt.

As soon as you start thinking of using a hack in production code, go take
a cold shower and lie down until the urge goes away.

Have you tried to find out why Py2Exe is broken and fix that?
