What version of Xenomai did you use? You need the head of SVN trunk (or 
take the snapshot):

  $ svn co http://svn.gna.org/svn/xenomai/trunk xenomai
  $ wget http://svn.gna.org/daily/xenomai-snapshot.tar.gz

See above. And with a recent version of Xenomai you have to use 
--arch=ppc (-arch=powerpc does not work any more for the ppc tree).

Likely you do just not use a recent version of Xenomai 2.3.x. It is 
working with my setup.
