Ahh, good -- when I read your first post, I was inclined to shoot back
with a "Sounds like a broken Python installation", but I know very very
little about Python on Windows so I kept my mouth shut. Looks like I
would have been right.
Should I add code somewhere in Distutils to detect empty sys.prefix or
exec_prefix? This really sounds like a clear indication that the Python
installation is badly broken, so there's no point in trying to install
anything because it simply won't work.

Yep, that's already been fixed. It just took me a couple of weeks to
get around to trying it out on a Windows machine myself. Now done. See
my next post...
