Comment (by RobK88):

 Thanks Chris!  The boot-strapped solution is the way to go!

 I uninstalled `libomp` and was able to reinstall it from source on Lion.

   libomp has the following notes:
     To use this OpenMP library:
      * For clang-3.8+, or clang-3.7 with +openmp variant:
         add "-fopenmp" during compilation / linking.
      * For clang-3.7 without +openmp variant, use:
         "-I/opt/local/include/libomp -L/opt/local/lib/libomp -fopenmp"
