Error: failed to retrieve bind-chroot-9.3.3-10.el5.i386.rpm from base
error was [Errno 4] IOError:

The main reason for these problem is yum server it is not find there package properly or there createrepo is not group there package properly
Proper way to createrepo in rhcl5
[root@dhcppc3 ~]#createrepo /var/ftp/pub/Server
First I miss there Server directory so I Got these problem.
Then I will give the proper path like /var/ftp/pub/Server
Finally it will work properly.

Then in /etc/yum.repos.d/
In there yum configuration please give the proper Baseurl like /var/ftp/pub/Server
If you did not give proper things the it will display the error
