We definitely don't want a run dependency on eg++ for the Qt5 package. This is mostly setup for doing builds as part of ports. And in that case, if you're writing a port which uses Qt5, you would set MODULES=x11/qt5 which automatically inserts a link or wrapper for the correct compiler at the head of the path so that calling it as 'g++' works.
