ghostscript and ly 2.12.2 broken? vserver architecture misidentification with uname -m

[Rob Canning]

hello!

suddenly i have a problem which appeared yesterday - perhaps something 
upgraded ghostscript (Ghostscript 8.70 (2009-07-31)) and now there is a 
problem on lilypond 2.12.2:


Layout output to `test.ps'...
Converting to `./test.pdf'...
`gs -q  -dSAFER  -dDEVICEWIDTHPOINTS=595.28 -dDEVICEHEIGHTPOINTS=841.89  
-dCompatibilityLevel=1.4  -dNOPAUSE -dBATCH -r1200  -sDEVICE=pdfwrite 
-sOutputFile="./test.pdf" -c .setpdfwrite -f "test.ps"' failed (256)
error: failed files: "test.ly"

should i downgrade ghostscript or what is the solution?
i am on ubuntu karmic

i thought i would upgrade to the unstable version to test compatability 
there but there is no deb yet so two questions:

i am running a 32bit ubuntu karmic vserver on a 64bit debian host -
so the architechture is misidentified by the arch=$(uname -m) in the 
install .sh script

i tried to fool it by commenting that out and :
arch=i686

then i get this:

untarring lilypond-2.13.49-1.linux-x86.sh
bzip2: (stdin) is not a bzip2 file.
tar: Child died with signal 13
tar: Exiting with failure status due to previous errors

----------------------------
plan B is to try building a 2.13 debian package in my launchpad ppa - i 
dont have much hope for this but i am going to give it a go ... 
currently cloning the git repo...

--------

too much for one email

to sumarise is there a quick fix for this ghostscript problem?

thanks
