[R-sig-hpc] Problems Installing Rmpi on openSUSE 11.1 x86_64

[Hao Yu]

Hi Melwin,

Did you try

R CMD INSTALL Rmpi_0.5-7.tar.gz --configure-args=--with-mpi=/path_to_lam

Your system may have several mpi and Rmpi did not find a right mpi.

BTW, when you are installing lam, make sure to turn dynamic lib on. The
default one is static one and Rmpi needs libmpi.so to work.
