Undefined control sequence. \embeddedps

[jim smith]

I am running Lilypond 2.2.2 on FreeBSD.  It was running fine, then
I had to upgrade the tex system to gain some added functionality for
LyX.  Since upgrade teTeX, lilypond [actually, LaTeX] is now broken.
On FreeBSD, tex-latex2e is deprecated for teTeX-texmf.

While I know this is mostly a LaTeX problem, it looks to me like there
is something going on with either lilyponddefs.tex or lily-pdf-defs.tex
to produce this error [I think I've captured the germane part of the 
error message, produced with -V]:

The beginning part of the .tex file looks like this:

So, where do I begin looking?  Go straight to <comp.text.tex>?  Thanks 
for any help you can provide.
