"ruby"??? "mxcl"???

What does this have to do with R? (Or for that matter, the directions referenced?) Generally Simon advises against using brew, fink, or other Mac/NIX package installers. Rmpi is not listed as available in CRAN at the moment, apparently because it took more than 30 minutes to unload:


You should do a better job of explaining your system and resources and goals of this effort.

I doubt that you need to do any of that. Certainly you need to do a better job of describing your OS, your system tools, which MPI you have installed or are intending to use, and what versions of R and Rmpi that you have. 

Also explain why you are not using the standard parallel package.
