Thats because there is probably a compiled ob-lilypond.elc that wasn't updated and is loaded instead - right? > I also wonder: is it a good idea for me to be meddling in a file like > "ob-lilypond"?

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 am a beginner here, so thank you for your help! 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. -- cheers, Thorsten
