One thing you might want to try is blowing away that prefix dir and
reinstalling OMPI 1.3.1. I'm not confident that "make uninstall" does
an adequate job of cleaning things out. The problem is that there are
major differences between 1.2.x and 1.3.x, and the uninstall may well
miss some things as a result.
Easy place to start, at least. ;-)

I regularly run jobs like that on 1.3.1 - it has no desire to use

That sounds strange. I'm just going back and forth between OpenMPI
1.2.9 and OpenMPI 1.3.1 by using make uninstall/make install, and I
can always reproduce the behavior.
It sounds like something strange is going on in your environment
that makes OMPI think it is launching on a remote host. Most likely
cause is
something in your Ethernet configuration. Can you send us the
output of ifconfig (or whatever your equivalent is)?
Ok, here is some information on my system:
* Kubuntu 9.04 (Jaunty) alpha 6
* Core Duo CPU
* I have compiled both OpenMPI versions (1.2.9 and 1.3.1) myself,
using
configure --prefix=$HOME/software --enable-shared --enable-static
