I always get frustrated while installing readline package for rvm and need a bunch of googling for successful installation. So I thought of no more googling for this stuff and I just noted step by step procedures for doing it with ease. This post assumes that you already setup rvm and ruby on your workstations and using Ubuntu.
The Prerequisites
You need to install the following packages as prerequisites for readline package. Choose the prerequisites according to the Ubuntu version.

Common for both Ubuntu 11.10 and Ubuntu 11.04
ncurses-dev package is common for both Ubuntu 11.04 and 11.10.
