PNG output cannot be created with Mac OS X version of Lilipond 2.18.2-1

[Jun Tamura]

I believe that this is nothing to do with lilypond itself but the way gs
(ghost script) included in the Mac OS X application bundle was built.

Here is the command lines and messages from lilypond:

$ cat test.ly
\relative c' {
  c
}
$ /Applications/LilyPond.app/Contents/Resources/bin/lilypond
-dno-point-and-click -ddelete-intermediate-files --png -dresolution=300
