You're right: when I remove cmake, it builds just fine.  Thanks!

Thank you -- though I wonder if SLEPc should just be arch "any" so that
as other arches start to work for PETSc, such as kfreebsd-*, SLEPc will
automatically build.  (For that matter, I should enable s390x in PETSc
for the same reason -- as soon as PVM works on that platform, scalapack
will be available.)

Do you want to go ahead and upload?
