Does this failure still occur with Python 2.5a2, or the
current SVN trunk?

I'm trying to get a copy of OS X 10.3, then will try to
install it and look after this problem.
OTOH, the ctypes loading code is currently rewritten in the
upstream version - this will probably prevent this failure.

In the meantime, can you try to find out the cause of this
failure?  Would RTLD_GLOBAL instead of RTLD_LOCAL work? Is
the library file missing?
