Maybe the compilers portgroup indeed does part of what you want, but you would still have to provide the logic to tell when to switch to a particular variant. MacPorts doesn't support building ports with gcc (in particular not for the sake of supporting C++11). It might work if no C++ interfaces are used in dependencies / dependents, but your ports might crash if Qt5 is built against a differest libstdc++. MP officially supports using libc++. Problems are still to be expected even then, but it makes more sense to build the port with clang against libc++ than to suggest using gcc. Mojca
