Thats because there is probably a compiled ob-lilypond.elc that wasn't
updated and is loaded instead - right?

Not such a good idea, you should rather put
,----
| (setq ly-nix-ly-path "/usr/local/lilypond")
`----
or whatever in your init file and revert the changes in
ob-lilypond.el. If you want to hack the library, better clone its git
repo and create your own branch for experimenting.

I would say try the above, i.e. restore ob-lilypond.el and set the
variable in you init file. Alternatively you could delete the
ob-lilypond.elc and the do M-x byte-compile-file on the modified
ob-lilypond.el, but I would not recommend mess around in libraries for
customizations.
