Install capistrano on RHEL or CentOS

Capistrano is great for automating system tasks. Here is how to install it on RPM-based systems:

# yum install ruby rubygems
# gem install mocha echoe rake capistrano

Please note that mocha, echoe are optional for tests, but I included them in these instructions.
