Answer 1

For Red Hat systems, you can install the pre-requisites like this:

sudo yum -y install make gcc ruby-devel

and it should correctly install the dependencies you need for a native gem install.

This assumes you have Gems already installed, if not, install that as well:

sudo yum -y install rubygems

(Tested on an Amazon EC2 instance, which uses yum.)

Answer 2

It looks like you're probably using Ubuntu. Make sure to install the ruby-dev package for the Ruby headers.

sudo apt-get install ruby-dev

Alternatively, you may look into using RVM to handle Ruby/RubyGems instead.

Answer 3

For your ubuntu you need to install:

ruby developer packages

sudo apt-get install ruby1.8-dev ruby1.8 ri1.8 rdoc1.8 irb1.8
sudo apt-get install libreadline-ruby1.8 libruby1.8 libopenssl-ruby
