How do I force the package manager to re-install a package?

Or the entire Development tools package?

The G77 Is missing – and when I ask it to install – it states that is already installed.

Assuming you have satisfied the concerns Ignacio Vazquez-Abrams raised and still want to proceed...

Change to the directory containing the package[s] and do:

rpm -Uvh --force <package1> <package2> ... <packageN>

Note that this is pretty ugly and should only be necessary if things are messed up badly, such as when files have been manually removed outside the package management system, or when failed updates leave the RPM database corrupted.
