Yeah, I'm more certain SLEPc is the problem.  In the new release they
abolishing SLEPc.pc, renaming it slepc.pc.  Since pkg-config is
case-sensitive, the unexpected change is causing problems. 

Notice how the reported error is only with dolfin64. Because the
proper SLEPc is not detected, the 64-bit build is mixing up 32-bit and
64-bit builds of PETSc and SLEPc.

Resolution in progress.
