You are not necessarily getting the Rmpi .Rprofile. To use it, you need
to copy it to your startup directory, or link from there. Or you need
to set an environment variable or use an R command line option.
On Debian Lenny, r-cran-rmpi (thanks to Dirk for the packaging) has the
file at /usr/lib/R/site-library/Rmpi/Rprofile
As others have said, you don't necessarily want to use that profile; it
depends on how you want to use Rmpi.
