Martin, On OS X your singular package almost, but doesn't exactly work. Basically it gets names libsingular.dylib. However when SAGE looks for it, it looks for libsingular.so. See the sessions below. If I just make a symlink libsingular.so --> libsingular.dylib then your code works, so you're very very close.
