(CCing the R-devel list, maybe someone will have a better answer.) To be honest, I don't know how to. I wasn't able to configure R to use OpenBLAS using the configure script and options on my Linux Fedora system. I configure it without external BLAS, then replace the libRblas.dylib (.so in my case) with a link to the OpenBLAS dynamic link library.
