Hi David, It is entirely possible that you've found a bug, Mac OS X should work the same as linux et.al. in this regard. Does the module itself have any dependencies that possibly are not being found (check with otool -L mymodule.0.so)? If that is not the case, please send more info (if you like you can send me the project offline and I'll look into it).
