I managed tio install Rmpi and to load it, but I get the following errormessage when I try to create an MPI cluster and R hangs (no response):

[head001:15781] mca: base: component_find: unable to open osc pt2pt: file not found (ignored)
> library(snow)
> cl <- makeCluster(2, type = "MPI")
Rscript execution error: No such file or directory Rscript execution error: No such file or directory

I am using the following version:
