Ask yourself this: is your use case so *very* important that users who are
not as advanced as you --- which is to say, most of the MacPorts userbase
--- should be inconvenienced or even be left with a broken system, so that
your use case is slightly easier?

(If you think the correct answer to that is "yes", I don't want to know
about it. Just to be clear that as soon as you want to set the compiler to
suit yourself, either you are a macports dev or you are not the target
market for macports.)
