Just a heads-up for all LilyPond users: Updating Ghostscript to the most recent version (10.02.1) in MacPorts will break LilyPond.[*]
If possible, please wait until newer LilyPond versions (2.24.3 and 2.25.10) are available in MacPorts, which should happen soon. If everything fails you might fall back to using the stand-alone x86-64 Mac binaries from lilypond.org. Werner [*] This Ghostscript security fix unfortunately removes functionality used by the LilyPond's PS output.
