Sometime on Jan 21, Kinjal Sonpal assembled some asciibets to say:
Error : The current version of rpm only supports packages
having major number <= 3.
This is in the archives. You need rpm version 3.0.5 or 3.0.6 first. That will allow you to install other stuff.
When it says packages having major no <=3, that refers to the version of rpm used to create the package, not to the version of the software inside the package.
