yup -- that will confuse things.

could be -- I'm clueless on that one, but if I try in it:

 >>> import PIL._imagingft
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
ImportError: 
dlopen(/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/PIL/_imagingft.so, 
2): Symbol not found: _inflateEnd
   Referenced from: 
/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/PIL/_imagingft.so
   Expected in: dynamic lookup

What I don't know is if we should expect -imagingft to b importable all 
by itself, first. Though I wouldn't think it should depend on TK.

If I do:

 >>> import PIL._imaging
 >>> import PIL._imagingft

it works fine -- which makes sense --you'd never need to import 
_imagingft without importing _imaging first.

yes -- that's correct.

I'd say if all the self-tests run, you're in pretty good shape.

Try the enclosed test, too -- it uses freetype, without TK (at least not 
explicitly)
