compiling R 2.15.0 to link to open MPI

I use R in parallel on a cluster. Our Sys Op has compiled the versions for me, up to R 2.13.1 against openMPI libraries so that I can run programmes across 404 cores. I've just asked him to compile 2.15 for me but he can't find how to connect it to openMPI. Has that capability disappeared or has the method of connecting changed? Thanks J
Hi Jim: Well, from my experience, you don't link OpenMPI/MPICH2/etc. with the R binary per se. You build R the usual way. And, then you do an R CMD INSTALL Rmpi.tgz At that stage, you will need to be concerned with whether the appropriate headers and libraries exist. This step will give somewhat informative feedback about that. Rodney
