We don't have any guile experts in Ubuntu that I'm aware of, so we're
ourselves dependent on Debian for this.  Rob Browning appears to be
working on it:

  http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=615479

According to that bug log, he's blocked on a problem with libgc.
Perhaps somebody knowledgeable could help him out?
