I couldn't remember how I got lilypond-mode working when I first
installed it, but I found the web page I'd used before:

http://www.geoffhorton.com/lilymacs.html

I think what I'd done was pointed emacs at the lilypond-mode files in
/usr/bin/lilypond (or somewherelike) instead of copying those files to
~/.emacs.d. So when I removed the original installation, the library
disappeared, too.

I've got it all working again now, and copied the files into my home
directory's .emacs.d, so hopefully my next upgrade will be easier.

Thank you!
