From my experiments, this is where LilyPond's relocation kicks in. I
think you have to provide .reloc files in etc/relocation, that's also
what GUB does. It allows to dynamically set environment variables, in
this case GUILE_LOAD_PATH.
To point you to the next error in advance: You have to do the same for
Fontconfig or it can't find its config file 😉

Hope this helps,
