    I don't understand why this would be. The PF stuff is in the Vec  
library.

PetscErrorCode PETSCVEC_DLLEXPORT  
PetscDLLibraryRegister_petscvec(const char path[])
{
   PetscErrorCode ierr;

   ierr = PetscInitializeNoArguments(); if (ierr) return 1;

   PetscFunctionBegin;
   /*
       If we got here then PETSc was properly loaded
   */
   ierr = ISInitializePackage(path);CHKERRQ(ierr);
   ierr = VecInitializePackage(path);CHKERRQ(ierr);
   ierr = PFInitializePackage(path);CHKERRQ(ierr);
   PetscFunctionReturn(0);
}

The PF is suppose to work in the same way as the IS, I'm guessing the  
IS works properly?

   Thanks
