I'm not sure if "Pillow was converted to an egg" is an accurate =

description of the problem. To me, converting to egg is synonomous with =

"from setuptools import setup" (vs. from distutils import setup) which =

is a change that happened in Pillow. But there were other changes like =

removing "PIL.pth" which I think is what is actually responsible for =

the inability to do:


>>> import Image


This was intentional.

That sounds like reverting one of the major changes facilitated by the =

fork, which I don't think is likely to happen. If you can do:


>>> import Image


you are using PIL, not Pillow.
