Yes, that is best. OR: you can install into a whole separate tree and ignore the first installation.

If you don't have write access into the installation tree (i.e., it was installed via root and you don't have root access), then your best bet is simply to install into a new tree. E.g., if OMPI is installed into /opt/openmpi-1.6.2, try installing into /opt/openmpi-1.6.5, or even $HOME/installs/openmpi-1.6.5, or something like that.
