The key point is that you can't use "--with-hwloc-prefix=system" after
apply this simple patch.

When "--with-hwloc-prefix=system" used while configure,
mvapich2-2.3.4/src/pm/hydra/ will be compiled and linked with system
hwloc-2.x. Without "--with-hwloc-prefix=", mvapich2-2.3.4/src/pm/hydra/
will configure and build
mvapich2-2.3.4/src/pm/hydra/tools/topo/hwloc/hwloc .

Thanks
