Just the opposite, actually.  That code has been *added* in newer
libMesh, and hasn't made it into an official release yet.  You may
have to switch to using the git HEAD unless you want to wait for us to
get 1.4.0 out.

Serial.  I'm afraid Parmetis is our only currently available
partitioner for a distributed mesh.  Some of the others might be able
to work on a seralized DistributedMesh.
