Right.  I’ve been trying to understand what goes on in there.

Oh, that variable is set by LilyPond?  Awesome; that will make my life
easier.

I’m not sure it’s all working properly, though.  It seems like relocate is
setting the Guile library path correctly, and I’ve also set

it’s in the appropriate directory.
