On Debian/Ubuntu, I had to 'freeze' LAM at 7.1.1. It failed with the newer
ones, incl 7.1.4.  I never really looked too hard why ... as the plan was to
migrate to Open MPI as soon as feasible.  And I am happy to report that the
newest Rmpi, with one small additional change that should appear on CRAN
soon, builds fine against Open MPI.  If you can, consider migrating from LAM
to Open MPI.
