Shame on me!  It's fixed now in the CVS (`tex-html' should be
`texi-html', so you get the described error -- can someone please add
a guard to lilypond-script to make it default to, say, `texi' if an
unknown format is used?)

The default value for LILYPOND_BOOK_FORMAT is set in
lilypond-vars.make; it defaults to `texi' for speed reasons.  For web
builds, it should be overridden with `texi-html' to produce PNGs also.
As mentioned earlier, I don't know the `correct' way to fix the
Makefiles, so I tried the simplest solution I could find.
