Excuse my Phone spellcheck

I was able to build Lilypond on Catalina, using the newest Xcode. MacPorts does 
not yet have a distribution for Catalina, so I built it from source as well. It 
seems to work fine. I did have to make one change to the Portfile for 
lilypond-devel. I added macports-gcc-9 at the top of the 
compiler.fallback-append list, because MacPorts was mistakenly trying and 
failing to build gcc8 as a dependency. I know there is a political controversy 
about the GNU License and the latest Xcode, but there don't seem to be any 
technical challenges to building from source on the current Mac OS and Xcode.

I'm using a 64-bit-compiled Lilypond 2.19.83 on Catalina now.
