sudo port uninstall clang-4.0 llvm-4.0 should do it for you. don't forget to change the line in macports.conf about default_compilers, removing clang-4.0.
BTW I appear to have fixed clang-4.0 for snow leopard, and depending on what Jeremy wants to do with that, it should be working in macports or upstream eventually. Although I'd recommend you stick with clang-3.8 or clang-3.9 for now, clang-4.0 for snow leopard will work soonishly.
