I think that this problem still exists. From what I have found out so far (still I don't have access to osx 10.3 myself), it seems that there are three possibilities: - ignore this issue ;-) - make RTLD_GLOBAL the default mode on osx: either on 10.3 only, or on all versions (how can I determine 10.3 from 10.4?) - change the *test* only so that RTLD_GLOBAL is used on osx. I do not know how other ctypes users on osx are affected by this problem, however http://codespeak.net/pypy/dist/pypy/doc/rctypes.html#ctypes-version-and-platform-notes recommends to patch ctypes/__init__.py on osx 10.3.
