I think you should go back a step and see if you can run a standard 'hello,
world' MPI example. If and when you can, then try installing Rmpi.
Some of us work reasonably hard to provide all this via a simple apt-get
without further ado, hassles or worries. You don't have to tear your hair out
over this, depending on the platform you choose.
