Hi James,

It's best to post Boost.Python questions to the c++-sig:

I don't know much about MacOS X, but I'm guessing there's an
LD_LIBRARY_PATH or some such that tells it where to look for
dynamically linked libraries?  If so, you need to modify it to point
at libboost_python.dylib, or move the library to a location already in
that path.
