Comment (by ryandesign):

 Also, there's the mkvtoolnix-devel port Chris created two years ago to try
 out a different strategy of using macports-libcxx to allow the latest
 version to be used on more systems, so that Portfile is already
 significantly different from the mkvtoolnix Portfile. I assume the
 intention was eventually to change mkvtoolnix to be like that. What's the
 status of this experiment? If it has been successful, maybe what we do is
 rename mkvtoolnix to mkvtoolnix-qt5 or split it out into separate
 versioned ports ("qt5" in the name wouldn't necessarily be accurate since
 older versions don't require qt at all) and rename mkvtoolnix-devel to
 mkvtoolnix and proceed with updating that to qt6.

 I note that currently mkvtoolnix-devel fails on all systems... was there
 an updated patchfile that didn't get committed?
