Re: [Rd] R CMD INSTALL configure.args and CC customization

One way to deal with this is to install R itself with mpicc. Then all packages are installed with mpicc and get the required MPI libraries and includes by default. I have done this with R-2.13.0 on an Opteron cluster running CentOS-5 a while ago and so far it has worked out great.

I crosspost to r-sig-hpc and welcome others to comment if there are potential downsides to this solution.
