[python-win32] win32com on activepython 2.3

[Jens B. Jorgensen]

I've heard another report as well. Someone used makepy.py to generate a 
wrapper for the visual sourcesafe typelib. This failed initially because 
the relocated genpy cache didn't have directories created (I believe I 
saw in the changelog this is now fixed) but even after that he got an 
error from the module when it was imported. It truly seems like 
something's broken in there.

Anyhow the error you're reporting is just the problem with the gencache. 
You need to create the missing directories in that path it lists for the 
gencache and that will solve that problem.
