Is /usr/lib/lam in your ld search path? This sort of message usually
means a shared library cannot be found. You do need lam-libs as well
according to yum.
R CMD ldd /usr/lib/R/library/Rmpi/libs/Rmpi.so
/sbin/ldconfig -p | grep /usr/lib/lam
might be illuminating.
There are various problems with the configure scripts in Rmpi for Fedora
layouts that the maintainer is looking into: it fails completely on x86_64
systems. I don't understand how your line worked: that looks for -lmpi in
/usr/lib/lam/lib/libmpi.a and that is not where FC5 puts the libraries.
