I reverted the change to ob-lilypond.el and did as you suggested, adding (setq ly-nix-ly-path "/usr/local/lilypond") It's now looking in the right place, but still won't tangle the file when I run ly-tangle. The message in the minibuffer is: ly-compile-lilyfile: Searching for program: resource temporarily unavailable, /usr/local/lilypond The use of "temporarily" is certainly intriguing! I quit out of emacs and restarted, but am still getting the message. Thank you for all of your help. I feel like I'm inching forward here ... !
