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.
