Hi,

I just found out that there are currently three people who try to get
lilypond to work with guile 2.0.12, but they hit a roadblock on the
guile-side:

From http://lilypond.1069038.n5.nabble.com/guilev2-work-was-LilyPond-boolean-syntax-true-and-false-td185707.html

Can someone here help Andrew Bernard and Thomas Morley build lilypond
with the self-built guile?

That LilyPond does not work with Guile 2.0 is like the worst case
scenario for Guile adoption, so it would be great if we could help them
get this moving again.

Best wishes,
Arne
