[CentOS] yum priorities and obsoleting...

Hey,

I ran into a yum conflict regarding an repoforge extra package obsoleting a base package.
The thing is that I set a lower priority to repoforge extra...
Any idea how come I ran into this issue...?

The question is more about the yum priorities than repoforge.
