OK I exported these variables and tried building Rcpp. I don't know if it used clang++ behind the scenes, but it appeared to compile with g++. To be sure, I downloaded and compiled R from source with clang++, and built Rcpp on top of that installation. It compiled successfully with clang++. So it works for me too. My system is Debian Sid with clang/llvm version 3.1.
