shared file locations in 1.3.77

[Jeff Grady]

I read the FAQ carefully, and I couldn't find this question, but sorry if this
has been covered elsewhere.  This should be an easy fix for a knowledgable
person.

I'l trying to latex a file that lily generated and I'm getting errors like:

! I can't find file `feta20.tex'.

It appears that latex can't find the files in /usr/local/share/lilypond/.
Where should they go?  Or is that not the problem?

Thanks.
