Installing rpy on redhat

I'm new to RedHat but have been using Ubuntu for a while. I am trying to install rpy2 using pip install rpy2

and I am getting the error

I know I need something called adns as mentioned elsewhere, but cannot figure out how to install on RedHat. I tried to download it and install it from a file, but it didn't work.
