Yes, I just build it with /usr/bin/python, and it works fine.
Assuming
you have Xcode 3.2 installed.

Ugh, this is getting messy...
I think that I have built libfreetype.dylib and libjpeg.dylib as
i386 and x86_64 libs...at least that is what the file command
asserts.
I then built the PIL package using the system python in 64 bit mode
and
installed the rascal in the Apple python. All of the libs appear to
be
multi-architecture ppc, i386 and x86_64
When I run apple python in 64 bit mode I can run the PIL demos...
If I restrict apple python to 32 bit mode all of the programs fail
with a bus error.

I then tried to build PIL using the 2.6.2 python from python.org.
1) It would not build under gcc-4.2 I had to define CC=gcc-4.0
the build appeared to succeed and I installed the PIL system.
2) All of the demos failed...
I noticed that _imagingtk.so was dynamically linked against
the ActiveState Tcl/Tk that is installed in /Library/Frameworks/
Tcl.framework
[mbp:/Library/Python/2.6/site-packages/PIL]$ otool -L _imagingtk.so
_imagingtk.so:
/Library/Frameworks/Tcl.framework/Versions/8.5/Tcl (compatibility
version 8.5.0, current version 8.5.4)
/Library/Frameworks/Tk.framework/Versions/8.5/Tk (compatibility
version 8.5.0, current version 8.5.4)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current
version 124.1.1)
I suppose that I could hide the ActiveState versions by renaming the
Frameworks...
But even if I did that, how could I force setup.py to use the apple
8.4 tcl/tk system instead
of the 'current' 8.5 system?
Any suggestions as to how I can get PIL to work when apple python is
in 32 bit mode?
Any suggestions as to how I can build PIL using the 2.6.2 version of
Python from python.org?
This is getting ugly...too many impedance mismatches.

A little more success to report. ..
I hid the activestate tcl/tk frameworks in /Library/Frameworks and
set CC to gcc-4.0
and rebuilt PIL and otool showed that _imagingtk.so was linked
against the apple 8.4
Tcl/Tk system.
So I installed the build and "tada" Imaging appears to be working in python.org
version
of python (2.6.2).
So this leaves only the "why does apple python (2.6.1) not work when
run in 32 bit mode
but does in 64 bit mode" question open...
Has anyone had success with PIL in this case?
Thanks
Jerry
When I run the Apple Python in 32 bit mode I get a bus error at the
same place when I try
to display an image using PIL . Here is part of the dump.

The crash occurs at the same 'place' every time...
If I run the Apple Python in 64 bit mode or the python.org Python ( 32
bit carbon 2.6.2 )image displaying, ie PIL, works fine :)
Sorta strange...
Here is a sample program that can be used...
