Hi Cayte -- I just looked at this using my little bit of Windows/python
knowledge. It looks like Thomas is importing posix/posixpath in all of 
the different modules in xbbtools, but never actually using them. I
commented out all of the imports, installed Pmw, and xbbtools seems to 
run okay on the machine I was playing on (vanilla Windows 98).

I'm not sure if there is a good reason to import the posix stuff
(Thomas?) but maybe if not, it might be good to get rid of the imports 
so it'll run nicely on Windows as well.
