Why? (You should not need to do this -- I never did (for years) ... until I decided to migrate to clang/llvm in stable/9 & head).

Perhaps if you were to provide the precise content of /etc/make.conf and /etc/src.conf, that might help. Also: Are you certain that your svn checkout or update completed successfully, so your src working copy is complete? FWIW, in switching to clang/llvm, I left /etc/make.conf alone (as I wasn't trying to switch to clang/llvm for ports at this time); rather, I set up /etc/src.conf: g1-227(9.1-P)[1] cat /etc/src.conf PORTS_MODULES=x11/nvidia-driver CC=clang CXX=clang++ CPP=clang-cpp WITH_LIBCPLUSPLUS=yes g1-227(9.1-P)[2] (That's on my laptop.)
