If LilyPond doesn't link to gs but only execs it, then gs having an
incompatible version of GPL from LilyPond's version should not render
either binary undistributable, even together.  GNU's position seems to be
that exec is a boundary across which it's not necessary for licenses to be
compatible.  Of course, whether MacPorts's automated determination of
distributability can capture this distinction, is another question.
