Can't install Yum Extender on Fedora Core 5
 

I recently did a clean installation of Fedora Core 5 onto an Intel Pentium IV system, and now when I try to install Yum Extender I get the following output:

# yum install yumex

What needs to be done so I can put Yum Extender on this system?

I remember having a similar problem in the past. I think I resolved it by doing,

When I try to execut "yum upgrade" I get the following:

What needs to be done to resolve these dependency issues?
