So parallel/openmp is not a solution for Darwin's crippled tool chain, 
since it requires pkgsrc llvm 10.  Xcode on Big Sur provides llvm 12.

Mac users will need to install OpenMP another way in order to use it 
with the native compiler for now.

I'm sure we could rig parallel/openmp to work with a native clang, but 
that's not a priority for me at the moment.
