Howto OSX + GUI + PIL1.1.3 ??

Is there an easy way to get Python Imaging Library 1.1.3 running with a 
GUI under OS X?  I am currently using PIL 1.1.2 with the W GUI package 
under MacPython, but am unsatisfied with the way it downsamples images, 
which has been improved in 1.1.3.

The PIL site <> has had the 
source available since March, with a "binaries will be available later" 
notice for 4 1/2 months, anyway I guess they mean Windows binaries since 
the Mac version was never at that site.  A newer MacPython has been 
released since then but it stuck to the older PIL for compatibility 
reasons.  I can't compile my own PIL even if I knew how because 
apparently getting extensions to work with MacPython has to be done with 
one particular compiler, CodeWarrior 8, while the only compilers I have 
are the gcc that came with the OS X developer tool CD and a much older 

Poking around on the net gives me the impression that Mac Python energy 
these days is going into something else called MachoPython, which uses 
different UIs (wx or tkinter).  Does this work better than 
tkinter/MacPython (which I could never get working well and when I asked 
about it was advised to switch to W)?  Is there any hope of working with 
W or would I need to rewrite all my UI code?  Does MachoPython allow the 
creation of standalone applications or applets onto which you can drag 
files?  Are compiled versions of PIL 1.1.3 available?  Failing that, are 
there clear easy to follow instructions for someone who has never 
compiled a Python extension?

Perhaps this should go to the MacPython list instead of here, but I 
didn't get much useful response when I asked a similar question there a 
couple months ago.
