I don't know how you are building that mpkg, but py2app has code that 
tracks dependencies on non-system libs, includes them, and re-writes the 
binaries to point to the new ones. I think macholib does the later 
magic, but know nothing of the details.

As it happens, I'm off to SciPy in a couple hours, and am going to join 
the MacPython sprint next Monday -- maybe I can find out more about how 
to do that there.

sure.

I don't need any of the Fortran stuff right at this moment, so I'll just 
comment out those imports for now.

thanks for working on this -- having a good binary for OS-X would be 
really nice.
