It works on git:
% macruby -e "p MACRUBY_REVISION"
"git commit 35e069811a44e9346b00cfbcccedc24ae7cce48f"

I'm not using export-subst, but when their is a .svn directory I'm  
calling "svn info" and if there is a .git directory I'm reading .git/ 
HEAD. "unknown revision" should only appear if there is neither a .svn  
nor a .git directory. I haven't looked at the scripts that build the  
nightlies but does it do a svn export or something similar? If that's  
the case, could we switch to a normal checkout?
