The RedHat EPEL team bundles jquery as part of the cacti installation for a nicer treeview. When a user installes the ReportIt plugin, this breaks the Cacti treeview becuase reportit has already loaded another version of jquery that is incompatible. By deleting jquery-1.4.2.min.js from reportit, the treeview begins working again. It is not sufficient to symlink that file to the jquery.js included by EPEL. The version of jQuery included by EPEL does not render the summary graph labels.
