With older versions - your best bet is to port this patch over and see if that works.

https://bitbucket.org/petsc/petsc/commits/77408d619c8

Or build hypre manually - using the additinal options enabled by this
patch [or check and the hypre config from the hypre build that the
current verison of PETSc builds and installs]
