It doesn't matter - 1.3 isn't going to launch another daemon on the
local node.
The problem here is that OMPI isn't recognizing your local host as
being "local" - i.e., it thinks that the host mpirun is executing on
is somehow not the the local host. This has come up before with ubuntu
- you might search the user mailing list for "ubuntu" to see earlier
threads on this issue.
I forget the final solution, but those earlier threads will explain
what needs to be done. I'm afraid this is something quite specific to
ubuntu.

I gather you must be running a version of the old 1.2 series? Or are
you running 1.3?
It does make a difference as to the nature of the problem, and the
recommended solution.
Thanks
