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)
