I've never heard of that happening before. macOS has never had a /run directory.

Is a path beginning with /run/user familiar to you? Do you have something special set on your system that uses such paths?

Does this happen with any other ports or just lilypond-devel? Maybe lilypond-devel's build system is doing something weird.
