So this is python. That changes things a bit.
The location of the python script doesn't matter, the executable (as far as the linker and dlopen are concerned) is the python interpreter, which is why it is in Contents/MacOS.

If you shell out to another program, though, (os.spawn, popen2,, etc.), that creates a new executable for linking and loading, and the easiest thing to do is to put any program that you need in Contents/MacOS as well.
