$(datadir)/.../dvips vs. .../ps

[Karl Berry]

In lilypond 1.6.6, using dvips(k) 5.90a (from TeX Live 7), I find that
music-drawing-routines.ps is not being found.  I added -d -1 to the
dvips invocation in ly2dvi, and found that it was searching for a
directory name `dvips' instead of `ps':

...
kdebug:search(music-drawing-routines.ps) =>
(full debug output below, fwiw)

I don't understand why this used to work and/or why it's broken now.
However, since I just want to typeset my music, I made a symlink
dvips->ps in $(datadir)/lilypond/1.6.6, and now dvips can find the headers.

Thanks,
karl
