Using clang-3.5 or later on OS X 10.8 or earlier is problematic because it forces the use of libc++. I'll test with clang-3.6, but it'll take me awhile to build it. Was a bug report ever filed with llvm, as the error message says to do? If not, that should be done. If there is a fix, it would be great to get it into llvm-3.4 at least so that libc++ is not required.",defect,closed,Normal,,ports,2.3.1,fixed,,,fswatch
