[Image-SIG] Mac support for PIL

[Bill Janssen]

Here's the fragment of my csh script which builds PIL.  I unpack PIL, libpng,
libjpeg, libfreetype, and libtiff in a directory, then build them with
this.  Note that the key in building PIL is to replace the reference to "/sw"
with the pointer to where you want to install it, in this example "/usr/local".
You may need to run this as sudo, depending on what else you've done to your
Python installation -- this one's keyed to the standard /usr/bin/python.
