I think we could fix the problem by having the port blacklist the compilers only when libc++ is in use (MacPorts base will then add newer clang compilers to the fallback list), and disable assembly when libstdc++ is in use.

Ok, so you changed it, but kept the darwin 12 version cutoff. What happens on darwin 12 with libstdc++? Why is that case special?

If the user has libstdc++ Mountain Lion with Xcode 4 (which has clang < 500) won't wavpack fail to build?
