Yes -- I happen to maintain GNU R, a number of R packages (eg r-cran-*) and
more for Debian and am also part of Debian's Open MPI maintainer group. I
also use Rmpi at work.
Dr Yu and I sorted out all relevant issues a few weeks ago and the most
current Rmpi (ie 0.5-5) works out of the box on Debian and Ubuntu, and is
current in Debian. It should "just work" on any other recent Linux and Unix
distro. If not please report back what configure reports and where it fails.
[ As an aside, we do have a current bug in Debian unstable with Open MPI as
we're trying to make transition between LAM, MPICH and Open MPI more
bullet-proof. If you use just Open MPI you should already be fine. ]
Greeting from Chicago, Dirk
