That could work, unfortunately one of the ports so affected is qt4-mac, which takes so long to compile that it would be awful to disable binary packages just for this reason.

All the compilers that come with Xcode are binary compatible. There is
no good reason to do this.

Anything that tries to use a nonexistent compiler is not respecting
configure.cc and friends. Fix that problem.
