Quick thoughts without any testing: the python.org 2.6.6 uses a 
MACOSX_DEPLOYMENT_TARGET=10.3.  Make sure you set it when building all 
your dependent libraries, too.   Make sure you use CC=gcc-4.0 (default 
on 10.5 but not 10.6) for all building.  Don't bother trying to build on 
10.3.9.  In theory, you should be able to make this work.  A standard 
python installer can be built these days on any of 10.4, 10.5, and 10.6 
that will work on 10.3.9 through 10.6 so there's a good chance that PIL 
should be able to be built similarly.  No experience with matplotlib or 
bdist_mpkg.
