how to make python load dylib on osx

Question

Trying to load a shared lib out of the current \'.\' dir in a unit test on osx.

What works on Linux and Netbsd there is a symlink _mymodule.so --> ../.libs/

Just use *.so as your module extensions in OS X too. I have a vague memory of not being able to load .dylib's and it turning out to be an issue with python itself. . . but I can't find the mailing list post now.

However, rest assured you're following standard practice by using *.so's even on OS X. The only *.dylib's in the entire framework are the libsvn_swig ones.
