yes, so it is that file that would need to be looked at by someone with
good LilyPond skills - the lilypond-user@gnu.org is always very prompt
and very helpful in this respect.

I think you may be installing from the repository provided by your
distro ... I have two versions of LilyPond installed on my machine, one
in /usr/bin:

/usr/bin/lilypond --version
GNU LilyPond 2.22.0

Which comes from Debian.
The other in my home directory:

lilypond --version
GNU LilyPond 2.22.1

this last one I will have installed using the installer from
lilypond.org. The 2.19.49 installer is at

http://lilypond.org/download/binaries/linux-x86/lilypond-2.19.49-1.linux-x86.sh


Using that you should be able to install it in your home directory and
then test if you can compile the files.
