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.

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.
HTH,
