I also noticed llvm-3.6 is now available in MacPorts, so I decided to replace llvm-3.4 with 3.6, and install clang-3.6 . After all, now that Apple provides clang-3.5 and my Linux rigs have upgraded to clang-3.5 too, there's little use to keep an older version, but more in having a newer version.

This is behaving as intended. cctools and ld64 default to llvm-3.5 on Mavericks and later, because that is the latest stable version of llvm. I expect this will be changed to llvm-3.6 when llvm-3.6 becomes the latest stable version.
