Dear Ubuntu developers,
I'm one of the developers or LilyPond (the GNU music notation application), 
and we heavily depend on guile (actually, large parts of lilypond are written 
in guile).

Now, in February, guile 2.0 was released, which has a much improved garbage 
collection (based on libgc), proper unicode support, compiled code and is MUCH 
So, we'd like to finally switch to guile 2.0 from guile 1.8.

Unfortunately, we depend on ubuntu packages of our dependencies (for our 
documentation writers and the bug squad, which we cannot require to build 
external dependencies manually; we even provide a custom ubuntu flavor called 
lilydev with all the dependencies in place). So, we cannot switch to guile 2.0 
until there are ubuntu packages available.

Do you have any estimate when guile 2.0 packages will finally be available for 
ubuntu, so that we can start the switch?


PS: We just got a message from a packages of another distribution, who was 
quite frustrated that lilypond still requires an outdated library, where the 
latest stable release has been available for more than half a year.
