installing emacs lilypond-mode

[Paul Scott]

I have installed LilyPond on another machine and haven't figured out how 
to get lilypond-mode for emacs going.

The manual (2.9) says do a "make install" from the source archive.  Does 
this mean that I have to get the source tarball?  It's been quite a 
while since I've had to do this and I don't remember needing the source 
to set up lilypond-mode.

TIA,
