The only supported compiler in MacOS which is capable of compiling c++11
code is clang, which does not yet have openmp support.
You may try to use GCC with macports, but AFAIK it does not work very
well. You can open a ticket at:
https://trac.macports.org/auth/login/?next=/newticket
And ask the macports maintainers to add an 'openmp' variant which could
be used with GCC.
