You need to be running a lilypond binary that was compiled with
--enable-debugging for it to work. Also, the regtest doesn't produce
a .ps for the graph, it just writes a text description to stdout (or
stderr, I'm not sure). You'll need to process that description with
"dot" (part of the graphviz package) to produce the ps.
