I suspect that my not changing my .bash_profile is indeed the
problem unfortunately I do not know were yum placed open's lib and bin
directories. I tried looking in /usr/local/ but did not find and
openmpi directory, I suspect this has something to my Fedora
distribution as apposed to the Debian bellow. Could anybody tell me
where I could suspect to find the directory to place in my profile on
a Fedora or Red hat system when installed through yum? Much appreciated.
