You don't have the required versions of RRDTool and MySQL. As per the installation manual, you need MySQL v5.5 and RRDTool v1.4. Those that come by default with CentOS/RHEL are not supported by Zenoss v4.
Also don't use "rpm -ivh" to install rpm packages, it is better to use "yum install" since it can fetch dependencies from other repositories (again, see manual). You must either use the autodeploy script or follow the installation procedure as documented in the installation guide.
