Tobias,
     Thanks for the clarifications. One other issue with regard to
the Graphite wiki. When I follow the instructions for getting the
cloog-ppl git...

cd cloog
git-init
git-pull git://repo.or.cz/cloog-ppl.git

I find that when I later try to update with 'git pull', I
get the errors...

fatal: 'origin': unable to chdir or not a git archive
fatal: The remote end hung up unexpectedly

You might want to update the Graphite wiki to cover that
as well. Currently, I have to delete the cloog directory
and repeat the previous steps to get the current cloog-ppl
git.
