			You can install OpenMPI on pretty much any flavor of Linux as follows:

			<source lang="bash">
			#!/bin/sh

			./configure \
			--prefix=/path/to/openmpi/1.4.3 \
			CXX="/usr/bin/g++" \
			CC="/usr/bin/gcc"
			</source>

	OpenMPI creates Fortran bindings ~~(but in case you haven't gotten the memo - no one uses Fortran anymore)~~.

Building Fat Binaries

	You will likely want to edit the script so that it doesn't build for the PPC architecture.		You will likely want to edit the script so that it doesn't build for the PPC architecture.

			Once you run the buildpackage.sh script, you can double check to make sure it installed correctly. Normally, you could run the command <code>file /path/to/mpic++</code>, but actually that's just a wrapper for your regular C++ compiler.

			To actually verify, open <code>/path/to/mpi/include/mpi.h</code> and look for two lines:

			<pre>
			#ifdef __i386__
			</pre>

			and

			<pre>
			#ifdef __x86_64__
			</pre>

			If they're both there, it means you've got a build and a header file that will work with either architecture.
