Lily 2.7.12 autopackages fail on my Debian sid

[Paul Scott]

On my Debian sid system (completely up to date) the upgrade autopackage 
for any x86 for 2.7.12 fails looking for the correct version of  Guile

The install version fails with:

address@hidden:~/music/stfrancis$ lilypond-2.7.12 --ps cityofgodE.ly
GNU LilyPond 2.7.12
ERROR: In procedure primitive-load-path:
ERROR: Unable to find file "ice-9/boot-9.scm" in load path

I was using 2.7.10.  I will now try 2.7.11
