RPM dependancies

[sakshale@]

Me again.

I installed synaptic: http://www.nongnu.org/synaptic/
and started upgrading items. I immediately ran into a problem. There is a long list of items tagged "Installed (obsolete)".

For example; psa-7.5.1-rh9.build75041216.14

When I go to upgrade some key items, such as perl, mysql, etc... all of the "obsolete" files are listed for removal.

What flags them as "obsolete"?
