在Centos 6.5上安装Zend Server CE

Question

I am installing Zend-Server CE on Centos 6.5. I am referring to this tutorial Installing Zend Server with Apache with manually setup process. When i run the command yum install zend-server-ce-php-5.3 then all is going well with downloading but I see some error at the end of this command. Here's a screen shot of the error http://www.tiikoni.com/tis/view/?id=515f1e4
