Comment:

 The openmp variant doesn't compile on OS X 10.10 with Xcode 7.0. I also
 tried install the "vanilla" clang-3.7 port first and use that to compile
 clang-3.7+openmp, but that also fails. In both cases I get this error:
 {{{

 Sure enough, libc++ doesn't exist
 /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/lib.
 Instead, there's something called libc++.tbd. I guess this error will "fix
 itself" once El Cap is released.
