What is REEL 5?
Is it a typo for RHEL 5? If so you could go to the http://rpm.pbone.net
web site. You can download and install the software packages there. Click on advanced search and click on the RHEL 5 button. Then you will be searching only for RHEL 5 rpm packages. While on this site, once a package is selected, you can right click on the link to the package and copy the url. It is probably a repository that you can use as an installation source.
