Yeah... I was just hoping...

No.  I'm clueless.  Thanks for trying to work this out.

Indeed.  I have just re-written it to (I thought) be able to run on Windows 
but all of my development and testing has been on Linux (where it seems to 
work pretty well actually).  You are the very first person to even see it I 
think (except the commit logs...). 

I really appreciate your willingness to look at this.  My hope had been that 
pyside and/or PyQt4 would work fine on Windows - so that is the only semi-non-
standard thing in the entire binding.  But it is failing at the very very 
beginning.  Which is... odd.

sigh...
