Damn, you are right. libpaper is listed on https://ports.macports.org/port/ghostscript/details/ (We build without it in the official binaries: https://gitlab.com/lilypond/lilypond/-/blob/master/release/binaries/lib/dependencies.py#L260 ) Well, that's too bad since there is no actual license incompatibility due to the use as subprocess, as already noted by several others. Not sure if MacPorts can be taught that. (And I wrote very wrong things in my previous emails: even in the official binaries, there is software under a non-GPLv3-compatible license, namely Ghostscript itself, which is AGPL. Sorry for that.)
