I am trying to install the R package "Rmpi" which needs libmpi. I've installed openmpi and lam in Centos 5.2:
[root@rab45-1 /]# rpm -qv openmpi openmpi-1.2.5-5.el5 openmpi-1.2.5-5.el5 [root@rab45-1 /]# rpm -qv lam lam-7.1.2-14.el5 lam-7.1.2-14.el5
But I get the following error message when trying to install Rmpi:
/usr/bin/ld: skipping incompatible /usr/lib/lam/lib/libmpi.so when searching for -lmpi
I'm not sure what else to install/uninstall to fix this.

Is Rmpi packaged somehow or are you getting it from CRAN?
The web site http://www.stats.uwo.ca/faculty/yu/Rmpi/ suggests it should work with either LAM-MPI or OpenMPI or even MPICH2
Have you installed the mpi-selector RPM and set it up? This will set up LD_LIBRARY_PATH to the selected MPI version. But I don't know if it will fix your issue.
