LilyPond 2.23.3 installer on MacOS 11

[Hans Åberg]

This is a LilyPond 2.23.3 installer, latest unstable release, for use on MacOS 
11, made from MacPorts lilypond-devel, available on the link below [1].

Does not work on earlier MacOS versions. Might possibly work on MacOS 12 if 
installed on MacOS 11 before updating.

It installs in /opt/lilypond/, with the program in /opt/lilypond/bin/lilypond, 
and /opt/lilypond/bin/ contains other LilyPond programs.

If you have already something installed in this directory, it may be prudent to 
remove it first. This can be done by the command
sudo rm -rf /opt/lilypond

It may be the case that 'lilypond' is best to be run from a script that sets 
LC_CTYPE=en_US.UTF-8 (which otherwise on MacOS is LC_CTYPE=UTF-8). It can be 
created and installed as follows:

In Terminal write (^D is <control>D):
% cat > lilypond
export LC_CTYPE=en_US.UTF-8
export LANG=en_US.UTF-8
exec /opt/lilypond/bin/lilypond "$@“
^D

% chmod a+x lilypond
% sudo -s cp lilypond /usr/local/bin/lilypond

The program can then be called by 'lilypond' in Terminal, as /usr/local/bin/ is 
in the system searchpath.

And do 'rm lilypond' if you do not want to keep the local copy of the script.
