Richard,
   I see the problem now and it confirms my fears about the loose version
control on gcc vs ppl vs cloog. I had built a cloog deb package against
a ppl2 0.11 package but forgot that and reinstalled the ppl 0.10.2 package.
This resulted in a build of gcc with...

I believe in the past I may have tested FSF gcc built against ppl 0.11 vs a cloog built
against ppl 0.10.2 and that worked. Apparently it is the inverse that breaks graphite
(ie FSF built against ppl 0.10.2 vs a cloog built against ppl 0.11).
