I've got a python GUI working with Tkinter, and I need to package it as
an executable file, preferably a single file.  I've got py2exe working
without the 'bundle_files' option, but when I add that option in
("bundle_files": 1), the built executable gives me the following error:

Fatal Python error: Interpreter not initialized (version mismatch?)

This application has requested the Runtime to terminate it in an
unusual way.
Please contact the application's support team for more information.

This happens when the compiled Python executes the line "from Tkinter
import *".

Any ideas?  I've trawled Google and Usenet, abut can't find anything much...
