[Image-SIG] IOError: decoder zip not available

The setup output looks fine, so my guess is that your script isn't
picking up the same build as the one you get when you run the test
script.  Running the following command in your PIL build directory and
your script directory will tell you what files Python are using:

python -c "import _imaging; print _imaging.__file__"
