Building Mac OS LilyPond versions automatically (Was : another 'wrong type argument' error )

[Jacques Menu]

Hello folks,

I’m a regular user of Mac OS, which I use for development, and will help with 
the creation of LilyPond versions with pleasure.

My last try at building LilyPond from the source code on my Mac Mini M1 failed 
due to a library not being ported yet to this architecture, but Jonas told me 
that this should come with the current efforts by the developers team.

Hope that helps!

JM
