I can see several choices
yup -- it's easy to do all or nothing with macport or fink, though I do
see folks using macports to satisfy the dependencies for some python
extensions -- I wonder how?
If 1 works good - 2 or 3 would take more time
4) Use the pre-built Universal Framework libs available from:
http://www.kyngchaos.com/wiki/doku.php?id=software:frameworks
I think UnixImageIO and FreeType will get you everything you need.
These are dynamic libs that are built so that they can be used as OS-X
Frameworks, and have a structure so that they fit in well with
traditional unix builds.
you need to do a bit of path manipulation to get the PIL build to find
them, but they work fine.
The downside is that your PIL will then be dependent on them -- which is
not a problem unless you want to distribute your PIL build.
I think it would be a good idea to establish these Frameworks as a
"standard" way to support these libs with MacPython extensions, but I
didn't get much interest when I proposed it, and I haven't had the time
to push it myself.
I edited PIL's setup.py to support using these Frameworks a while back.
I haven't got it tested enough to submit a patch to PIL, but I've
enclosed what I did with this message.
