F8 dependency hell with avahi

[Beartooth]

	I'm running F8 on a T30 thinkpad. Whenever I try to do yum 
update, I get :

=====		=====		=====		=====
Is this ok [y/N]: y
Downloading Packages:

Transaction Check Error:

Error Summary
-------------
	=====		=====		=====		=====

	I've tried everything I can think of to update or get rid of that 
avahi-0.6.17-1.fc7.i386 with the "fc7" in it, and nothing I know works. 
Pirut did claim to have removed it; but yum update still failed the same.

	What do I do, while I still can? Yum wants to change 124 
packages, including replacing a kernel.
