Yum Extender fot Centos 5
 

Hi
Only package from sourceforge will work
If you want you use DAG repo for more packages
make new file DAG.repo /etc/yum.repos.d
with this
[dag]
name=Dag RPM Repository for Fedora Core RedHat Centos
baseurl=http://apt.sw.be/redhat/el5/en/i386/dag/
gpgcheck=1
gpgkey=http://dag.wieers.com/rpm/packages/RPM-GPG-KEY.dag.txt
enabled=1

#this is for centos 5

yum extender is good for new users as this resolves dependencies itself

So... what exactly is your question?

PS: Dag wieers is not really a yum(ex) fan (and he's damn right, yum is plain horrible):

No.
The actual dependency checking + resolving is done by RPM + yum.
Yumex is just a GUI front to make yum even slower ;)
