Cobbler: Missing yum-utils

I'm trying to create a CentOS 5 repository, but it errors out because it is missing the the reposync executable. The question how do I get reposync is this a bug? Should'nt reposync come with the cobbler package?

cobbler repo add --mirror=http://centos.mirror.netriplex.com/5/updates/x86_64 --name=centos5-x86-64 --arch=x86_64
