Some progress in my problem: Samu Mäntyniemi kirjoitti:

After these changes MPICH2 1.06 +R-2.6.0+Rmpi 0.5-5 work on the single machine in the same way as my DeinoMPI installation: Correct number of cpu:s is detected and I can "mpi.spawn.Rslaves()" I will try to do this with two hosts next and see if there is more luck with MPICH2 than DeinoMPI.
