While this seems to work, we really need a setting in macports.conf to allow the user to
disable binary downloads by defeult. Besides the issue of the wrong compiler being used,
many folks would like to avoid the ancient llvm in llvm-gcc and use the most current
llvm in the newest clang compilers. The code generation is bound to be much improved.
