But isnt' it going to use whatever C++ R was configured to use? 
Typically, that's the one it was built with, and for the "official" R 
binary on OS X, that would be "CXX=gcc". Which, depending on the version 
of the OS, will be either gcc or gcc-llvm. If so, wouldn't one need to R 
from source with clang as the C++ compiler in order to test this?
