Well, I'm not a MacOS user – except doing regular updates for MacPorts (and checking/adjusting the LilyPond port if necessary), this computer isn't used for anything else. > Is a path beginning with /run/user familiar to you?

Maybe > lilypond-devel's build system is doing something weird. It seems to be a problem with the 'ccache' package/port on MacOS 10.7.5. After updating to current git (and running `port sync`), `port upgrade outdated` just tried to compile emacs 28.1, and exactly the same problem happened. How can I test most easily whether my assumption is correct? What is the recommended way to install an older version of 'ccache'? Werner
