can't find 'lilyponddefs'

[David Bobroff]

Suddenly I'm getting:

(/usr/share/texmf/tex/latex/psnfss/ot1ptm.fd) (lily-1124984714.tex
! I can't find file `lilyponddefs'.
l.25   \input lilyponddefs
                           
Please type another input file name:


Obviously this is happening with lilypond-book.  During the LaTeX run I
get the above error.

It happened on v2.1.25.hwn1 and I went ahead and updated from CVS,
compiled and installed.  Same story under v2.1.27.

It first happened after a hard re-boot.  I don't know if it is relevant
but it is the only weird thing I can think of that happened between the
time that Lily was working and now.

Ideas?
