Unless I miss something, the problem is that GUB installers have always 
usr/share/lilypond/current, while distro packagers (at least Debian and 
Fedora for sure) prefer replacing it with the actual version.

My guess is that you should change the script in a way that it can run 
lilypond to find the version installed and then the correct path for 
that installation.

GUB changes some version to current here:
https://github.com/gperciva/gub/blob/master/gub/specs/lilypond.py#L120

It was not an happy decision as you may guess from the comment:

I can't, it's a binary:

[~]$ file /usr/bin/lilypond
/usr/bin/lilypond: ELF 64-bit LSB shared object, x86-64, version 1 
(GNU/Linux), dynamically linked, interpreter 
/lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.32,

[~]$
[~]$ ls -lh /usr/bin/lilypond

I had already tried this and did not work.

Error condition:
No LilyPond installation found at or in
 /usr/share/lilypond/2.19.62.
Abort script.
