I didn't say that libc++ doesn't work – I didn't try that at all (I'm
not even sure I know how to do it; maybe I could create a new macports
installation with instructions posted by Jeremy a while ago). I just
said that using clang-3.4 doesn't help as that doesn't support all
c++11 features needed by cling.
