PDF has wonky note glyphs

[Jeff Smith]

I finally got my latex docs displaying very pretty in-line music
using lilypond-book in DVI. (Thanks for the hint.)

But when I produce PDFs from the DVI, the note glyphs are wrong.
I just get the stems, no note heads. 

For the record, my pdf generation path is as follows:

lilypond-book -f latex MySource.latex
latex MySource.tex
bibtex MySource
latex MySource.tex 
dvips -Ppdf -G0 -o MySource.ps MySource.dvi
ps2pdf MySource.ps

Any suggestions?
