I'm having difficulty on compiling PIL on Leopard. PIL used to compile
just fine with the system's python (2.5.1 I believe), but with
macpython 2.6 it breaks.
First of all, I get lots of warnings after almost all gcc calls during
compilation that I did't get before. Sample example:
gcc -arch ppc -arch i386 -isysroot /Developer/SDKs/MacOSX10.4u.sdk -
fno-strict-aliasing -fno-common -dynamic -DNDEBUG -g -O3 -
DHAVE_LIBJPEG -DHAVE_LIBZ -I/System/Library/Frameworks/Tcl.framework/

Another illustrative example:
gcc -arch ppc -arch i386 -isysroot /Developer/SDKs/MacOSX10.4u.sdk -

And then it fails with:
gcc -arch ppc -arch i386 -isysroot /Developer/SDKs/MacOSX10.4u.sdk -g -
bundle -undefined dynamic_lookup build/temp.macosx-10.3-i386-2.6/

Is there a fix for this?
