You are right, working with apple and C++ is often a mess. Up to now, llvm does 
not yet support openmp. It is coming but I do not see it fully implemented 
before next summer. If I want to use openmp I have thus to rely on the gcc 
which brings a lot of problems with it and from what I read on the R-lists most 
of the Mac Users suffer. I guess that this time a reinstall of R was 
unavoidable for most of us. I thought about using the xcrun —find gcc/g++ etc. 
to get what is needed in a Makevars but this does not give anything so far.
