The one I made works with LilyPond 2.19.10 - just tested. It may be different 
from the one you have.

At least in the past, I think that if one has not recompiled LilyPond for the 
font, key signatures won’t work. They do work with the built-in microtonal 
accidentals, though.

This was one I had in mind.

For those that do not know about these: it is basically a way to make sure that 
Just Intonation can be typeset; there is not enough of microtonal accidentals 
in the built-in set.
