yum exclude?

[Dave Stevens]

After upgrading FC1 to FC2 I copied the /etc/yum.conf.rpmnew over yum.conf 
then did yum update. Here is the tail of the voluminous output:

Resolving dependencies
.....Unable to satisfy dependencies
Package libselinux-devel needs libselinux = 1.11.4, this is not available.
Package gstreamer-plugins-extras needs gstreamer-plugins = 0.6.4, this is not 
available.
Package gstreamer-plugins-mp3 needs gstreamer-plugins = 0.6.4, this is not 
available.

I can't think of any reason I'd want libselinux or gstreamer and would happily 
do without them until I develop some need. But I don't know how to exclude 
them from the update.

Ideas?

Dave
