Hmm, you say you use lilypond-profile.sh, I hope you don't mean the
file buildscripts/lilypond-profile.sh. That file is just a template, 
the correct paths are found in buildscripts/out/lilypond-profile, 
assuming that you installed Lilypond using `make install'.

Anyway, if you go for the first solution (environment variables), 
the main thing is that the variable $MFINPUTS points to the 
directory where the feta*.mf files reside. If it is set correctly, 
'kpsewhich feta20.mf' should return the full path to the feta20.mf
file. The problem with this solution is that the generated .tfm
and .*pk files may end up in the current working directory (depending
on how your teTeX installation is configured). However, both Lilypond, 
xdvi and dvips should be able to find the necessary fonts. Note that
$MFINPUTS should end or begin with a colon, so TeX finds the default
fonts as well. 

If you prefer the solution described in the FAQ, see to it that 
$MFINPUTS is not defined and that you have ran the command
'texhash' as root. Once again, the command 'kpsewhich feta20.mf'
should return the full path where it finds the file.

The kpsewhich command is your friend when you want to find out 
which font file is actually found.

Both Lilypond and TeX+friends use the Kpathsea library, run
'info kpathsea' to learn more. There's also some general info
in the teTeX manual 'texdoc TETEXDOC'. As long as the .mf files
are found, all necessary .tfm and .*pk files are generated on the
fly if they can't be found.

The reason that you don't get the errors when you run ly2dvi is
that it sets the search paths internally. The problem with this
nice solution is that is sometimes hides the true setup problems
which have to solved anyway if you want xdvi and dvips to work.
By the way, does 'ly2dvi -P myfile.ly' provide functional PS file?

If you still can't resolve the problems, please send me a private
email with the exact commands you run and the corresponding output. 
Also, include information on where you have Lilypond installed and
how you have set the necessary environment variables.
