I have no time to try this myself.  If others report the same thing,
open a bug report on SF.  Until then, I expect it's a quirk of your
setup.  Those generally can't be tracked down except by sitting next
to you, and I have no time for that.

After unzipping PyGeo, what is left behind?  A directory named PyGeo
or just a bunch of .py files?

I think Art does all his development on Windows; it may be that he is
case-inconsistent in the spelling some module name and that that
causes the problem.  But I have no time to download PyGeo and poke at
it. :-(
