Yes, thanks a million, this solved the problem.

While Rmpi now works, there is another issue connected with this one:
I'm trying to use the papply package. However, when I do:

> library(papply)
> papply(list(1:10, 1:15, 1:20), sum)
        1 slaves are spawned successfully. 0 failed.
master (rank 0, comm 1) of size 2 is running on: behemoth
slave1 (rank 1, comm 1) of size 2 is running on: behemoth
[1] "Running serial version of papply\n"

Papply only spawns one slave and then decides to run the serial
version instead. I'm not sure how to tell it to use all the 64
processors available.
