[Image-SIG] PIL builds for Mac OS X

[Bill Janssen]

Here's a fuller excerpt from my build script, in case it's helpful to
someone.  This is part of how I build the Mac installer for UpLib --
one of the side-effects of installing UpLib on a Mac is a full-fledged
PIL installation in the system Python.

I unpack PIL and all the prereq packages in /tmp, and go to work.
${distdir} could be "/usr/local"; for UpLib I use
"/Library/UpLib/<VERSION>".  I'm omitting large chunks; I also build
Lucene, xpdf, htmldoc, etc.
