Location of CFF fonts

[Daniel Johnson]

After a great deal of struggle, I finally got 2.5.7 to compile and 
install yesterday on my Gentoo box, but I've had a few font issues.  
Whenever I run lilypond, I get this message:

warning: cannot find CFF/PFA/PFB font "emmentaler20"

The output lacks clefs, noteheads, etc.  I had other issues with fonts 
but I was able to copy the proper font resources from my build tree into 
/usr/share/lilypond/2.5.7/fonts.  Emmentaler does not come with PFA/PFB 
but rather has CFF (as well as otf) resources.  These are present in the 
build tree but I can't figure out where to put them for lilypond to 
find.  Anyone have any ideas?

P.S. Other than missing noteheads, the new output looks great!  The 
default text font has changed from Computer Modern to URW Century 
Schoolbook, I believe.  This could change the spacing when converting 
older vocal scores to the new version, though.
