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. -- Matthew Skala msk...@ansuz.sooke.bc.ca People before tribes. https://ansuz.sooke.bc.ca/
