this looks like the culprit alright - I guess Apple's distutils is a
little broken. Your fix seems fine. You might be able to change
'-framework System Python...' to '-framework System -framework
Python...' too, but then you'd probably want to get rid of the
-lpython2.3 stuff. The result you get is still using the shared
library, so I don't think there's much point in going down that
road...
FWIW I wrote an m4 macro for linking to python a long time ago for
ices0, which seems to work fine on OS X with the system python. It's
in the ices0 tarball at m4/xiph_path_python.m4, and attached...
