I find this surprising, since both MacPorts and Homebrew provide a 
LilyPond package. What are the dependencies missing on each side? Have 
you tried looking at their respective build definitions? The one for 
Homebrew is here:

https://github.com/Homebrew/homebrew-core/blob/HEAD/Formula/lilypond.rb

and for MacPorts it's here:

https://github.com/macports/macports-ports/blob/master/textproc/lilypond/Portfile

By the way, it's a very good idea (well, it's essential) to build 
LilyPond if you want to contribute to it, but for anyone just looking 
for native Apple Silicon binaries of LilyPond, just install from 
MacPorts or Homebrew. MacPorts is recommended for the time being because 
Homebrew uses version 2.22 with Guile 2. Since we did not support 
byte-compilation of Scheme code at that time, the Homebrew version will 
be slower (and in particular have bad startup time).

Best,
Jean
