The supporting technology for macports-libstdc++ did not exist in llvm until the 3.9 release.

I backported it into llvm-3.8 for my own use on PPC <https://github.com/kencu/LeopardPorts/tree/master/lang/llvm-3.8> but there was no reason to make that available for MacPorts so I never submitted it (and clang-3.8 has been deleted from MacPorts anyway now).
