David,

Thanks for adding a test for _tkinter.c.  It's a really good start.
Unfortunately, testPackageRequire() fails for me because I don't have
Tclx.  Is there any way to make the test more robust?

I also have a question about the implementation.  It looks like 
useTK is required to be an integer.  Is that correct?  I would have 
expected to be able to use any boolean value.

Neal
