Oi. My bad, and thanks for the clarification.

| The above is still gcc 4.2, Apple won't move from there due to GPL-v3 tainting any more recent version of gcc. Our best hope is clang. Did you check Rcpp against clang?

I had forgotten about the GPL-v3 issue. With that Apple will never ship a new
gcc. Ding it.

I only ever tried clang/llvm very casually which resulted in me not
succeeding.  We have gotten patches based on clang/llvm before though so
other have done this.

So if someone has a 'recipe' or Makefile for clang and Rcpp, I'd be all ears.
