Thanks, that gets me a lot further, all tests pass until I try to run the perlnatives tests:

Is it something to do with the fact that a *.bundle is created, not a *.dylib? I obviously don't know how all this is supposed to work, but in any case there really isn't a dylib in the folder where it looks.
