Here is a patch that I hope will fix this problem. Ronald
Oussuren suggested in private email to use RTLD_GLOBAL as
default library loading mode on OS X 10.3. He suggested to
use the platform module to find out the osx version, however
I don't like. Instead I found by examining platform that
gestalt.gestalt("sysv") returns the information I need.
I still don't have access to 10.3 (and Python does not
compile on the 10.2.8 sourceforge osx compile farm machine -
should I add a bug for that one?), so I cannot really test
the patch myself.

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?
