No direct experience with mpich2 on Fedora, but I think you can use ./configure --with-mpi=/usr/local/mpich2
from within the unpacked Rmpi tarball, or R CMD INSTALL Rmpi_... --configure-args=--with-mpi=/usr/local/mpich2 from the command line. ... is the tab-completion to the tarball, and /usr/local/mpich2 should be a path such that mpi.h is in /usr/local/mpichs/include/mpi.h. Some insight is in the configure.in file of Rmpi. Hope that helps! Sorry for the repost, Bin, meant this originally to reply to the newsgroup.
