The easiest way to develop lilypond is to execute the binary directly from the 
build tree (=source tree). In particular, I have a file ~/.bin/lilypond 
(~/.bin is in my $PATH) containing only:

#!/bin/sh
exec ~/lilypond/lilypond/out/bin/lilypond --relocate "$@"

Apparently, my lilypond tree is in ~/lilypond/lilypond/. Notice the magic 
thing here is the --relocate option, which tells lilypond to use the include 
and scm files from the directory of the binary.

This way, running lilypond on the konsole will simply execute the built 
lilypond binary from the build (=src) tree and use all include and scm files 
from the source tree, no installation necessary. Plus, I can always run the 
Kubuntu-installed lilypond 2.12.x by explicitly calling /usr/bin/lilypond.

Cheers,
Reinhold
