Problem with ChordNames

[Patrick or Cynthia Karl]

I am using LilyPond 2.19.15 on a mac running OSX 10.10 (Yosemite).

The following snippet (from section 2.7.2 Displaying Chords of the Notation 
Manual):

 \version "2.19.15"

\new ChordNames {
  \chordmode {
    c2 f4. g8
  }
}

fails with the following in the log file:

Drawing systems...
Layout output to `document.ps'...

"BitstreamVeraSans-Roman"="/Library/Fonts/Vera.tff"

Exited with return code 1.

This seems to be identical to a problem reported in 2011 (Can't embed font for 
chord changes), but the answer was that OSX 10.6.7 had a font bug.  Is this 
still the case?  Is there a workaround?
