[Yum] (no subject)

[Joe Joe]

I'm running centos 4.4, and when I run any yum command, I get a scriptlet error. From what I read online, this is a package error, but it occurs on every package, and every command.
 As you can see below, the error prevents the requested removal from happening. Any help is appreciated...
