complaints when using midi-only output

[Erik Sandberg]

hi,

when there's no \paper block but a \midi block in my \score, I get these angry 
messages, though everything works fine (apart from the other bugs I reported, 
of course :) )

lilypond: warning: no LilyPond output found for `foo'
Running latex...
Running dvips...lilypond: error: `dvips' failed (status 1)
lilypond: error: The error log is as follows:
/tmp/tmpbzXyRQdvips.errorloglilypond: warning: Failed to make PS file. Rerun 
with --verbose for a trace.
MIDI output to `foo.midi'...
