ly2dvi pdf output

[Graham Percival]

When I try "ly2dvi -p" (for pdf), then look at the PS output (which ly2dvi
makes as an intermediate step), I get a score without noteheads, clefs,
etc.  (the infamous font problem :)

When I do "ly2dvi -P" (for ps output only), my score is fine.

\score { \notes { c'4 } }


Here's the problem (I think):

#####(portion of stdout for ly2dvi -P; it works)
#####(the file was called "mao.ly")
Output written on mao.dvi (1 page, 4560 bytes).
Transcript written on mao.log.

----------

For some reason ly2dvi wants to use 8000 dpi when producing a pdf, but it uses
600 dpi when producing a ps on its own.  Shouldn't they both be 600 dpi?
