Also, setting 'Executable Extension' to 'bundle' in the project target settings doesn't seem to have any effect on the binary file contained inside Contents/MacOS/

I see the problem. I didn't know that by .bundle you meant an actual Mac OS bundle (a directory with stuff in it). Maybe there is a bug in the tutorial, #require can only deal with Mach-O bundles (created using the -bundle option of ld(1)), like C extensions in MacRuby.
