Can't build out-www/lilypond.pdf

[Kilian A. Foth]

I can't seem to build 2.7.7's user documentation:

  Converting to 
PNG.../usr/src/lilypond-2.7.7/share/lilypond/2.7.7/scm/ps-to-png.scm:110:3: In 
procedure rename-file in expression (rename-file file old):
  /usr/src/lilypond-2.7.7/share/lilypond/2.7.7/scm/ps-to-png.scm:110:3: No such 
file or directory
  lilypond-book.py: warning: `lilypond' failed (status 2) (ignored)

And it appears that neither can you, since the online version

  http://lilypond.org/doc/v2.7/Documentation/user/out-www/lilypond.pdf

is also an empty PDF.

(I apologize if this was already discussed, the list archive search
is down.)
