you can install OpenMPI which is packaged for your distribution of Linux,
for examply on SuSE use zypper install openmpi
or the equivalent on Redhat/Ubuntu
You probably will not get the most up to date Openmpi version,
but you will get the library paths set up in /etc/ld.so.conf.d/ and
the mpi chooser installed
Once you have this version of OpenMPI working properly you should
compile and install your own latest version.
I just checked - the latest version for SuSE 12.1 in the repository
