I had the exact same problem couple of days back on RHEL5.8 , It was because I was not able to connect to the http site from my site, it was blocked,
So I had to work with the network guys, to allow my id to access it, or you can try to manually get it(wget worked for me) and bring it into your yum repo. and then re-try the cmd
The above worked for me.
