The context was wrt the OpenMPI version that is bundled with a specific
version of CentOS Linux which my IT folks are about to install on one of
our servers. Since the most recent 1.4 stream version is 1.4.3, I'm
afraid that 1.4-4 is really some variant of 1.4 (i.e., 1.4.0) and hence
not that new.

Is this an RPM version number? It's fairly common for RPMs to add "-X"
at the end of the version number. The "X" indicates the RPM version
number (i.e., the version number of the packaging -- not the package
itself).
Open MPI's version number scheme is explained here:

ompi_info | grep 'Open MPI' should tell,
(*If* you know to which version your ompi_info is pointing to!
Otherwise, use full path.)
Here is yet another reason for installing OpenMPI
from the source tarball
(you'll be 100% sure it is 1.4.3), and put it in a non-system
directory of choice, such as ${HOME}/openmpi/1.4.3.
My two cents (which were not asked for).
