Use otool -L to see what version of python and libjcc.dylib your  
executable is linked against.
Crashes like that usually hint at a version mismatch. If you built  
python 2.6 into a non standard framework location, you must use -F in  
jcc's LFLAGS to ensure extensions are linked against the correct  
version of things. In particular, libjcc.dylib is at version 2.0.0  
right now.

Fwiw, I've got a happy python 2.6 PyLucene running on my mac.

On mac, unless you changed JCC's LFLAGS, the build assumes a framework  
build of Python (configured with --enable-framework=path)
