Your problem might be confusion about 32 versus 64 bit packages.

Let me guess - you're running a 64bit CentOS (this would explain why the 
packages are listed twice)?

To find out about 32/64bit packages it helps to have the following line 
in file /etc/rpm/macros:
%_query_all_fmt %%{name}-%%{version}-%%{release}.%%{arch}

Make sure to install the correct version (32 or 64bit) of Rmpi, and to 
tell Rmpi correctly where it should look for the mpi library.
