I cannot support non-Free OSes, but you should check that error message
again and see if GCC4 is used or install the atomic_ops library.

I have heard of newer OSX use a LLVM-based compiler that's not 100%
compatible with Ruby 1.9 itself, either.

Maybe somebody else on this list has more knowledge of non-Free OSes.
