You shouldn't need to, no. I'm guessing you've got a cruddy version installed from somewhere else, else the yum install would have just worked, but I'm just guessing as you've not posted anything to say what happened when you tried the yum install. rpm -q rrdtool Possibly: yum --disablerepo=\* --enablerepo=base downgrade rrdtool yum --disablerepo=\* --enablerepo=base install rrdtool-devel rrdtool-perl This may also clear up where you are: yum list rrdtool --show-duplicates jh
