How to install Mercurial on my Red Hat Linux machine without using “yum” command?

Question

I have been trying to install Mercurial binary packages on my Red Hat Linux machine. According to the install instructions, I should type command "yum install mercurial". However, in order to use the "yum" command, I need to first register my system with RHN(Red Hat Network). I tried a couple of times but still failed to do so.

Beside waiting for Red Hat representatives to help me register, I am wondering if there is some way for me to use "yum" command without registering to the RHN. Or even better, can someone tell me how to install Mercurial without using "yum" command ? I have used only "install" command to install it but it didn't work. It is really frustrating~

Thank you very much,
