scheme problems on ppc

[Graham Percival]

Debian etch, linux/PPC, git head.  I have no trouble compiling this file 
on OSX/intel.  I had some trouble getting international stuff set up 
(well, I forgot that I needed to install the packages), but now files 
such as input/regression/utf-8.ly and input/sakura-sakura.ly are working 
fine.  This _is_ a new system, and the first time I've ever tried out 
the linux binaries, so I might be missing something obvious.

I don't have guile installed, so lilypond is using whatever guile 
currently comes with 2.11.22.  I'm using the ppc binary, and other files 
compile fine.

file typography-demo.ly returns "UTF-8 Unicode text"
