Please file bugs for that, I'm pretty sure that ctypes is supposed to implement the same algoritms as the platform dynamic linker.

W.r.t. py2app: I consider cases where py2app doesn't find modules or shared libraries bugs and should be fixed, either by making the core smarter or by adding recipes.   Please post reports about issues, especially when you can reproduce them in smallish examples (or at least examples that you can share with the outside world).

Yes, but that will require some additional trickery to ensure that ctypes looks in this special location before looking at the full name specified by the caller.

Actually finding which libraries are loaded using ctypes will sadly enough be impossible in general, although recipes could be used for the popular libaries.
