And actually that is the only difference. /usr/bin/python and 
...../Python.app/Contents/MacOS/Python could have the exact same bits.

Then it could be you're running up against a completely different 
problem. Does the hosting application have its own GUI mainloop? 
Because if it has (and note it could be implicit, if you use Cocoa or 
CarbonEvents)  then you will probably run into problems with your 
mainloop and Tk's mainloop getting in each others hair.
