LilyPond 2.21.1 installer on MacOS 10.15

[Hans Åberg]

I made a LilyPond 2.21.1 installer for use on MacOS 10.15 from MacPorts 
lilypond-devel, available on the link below. It installs in /opt/lilypond/, 
with the program in /opt/lilypond/bin/lilypond.

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 -r /opt/lilypond

It may be that it is best to be run from a script that sets LC_CTYPE=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

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