title: How Can I install ruby on Redhat? ruby package not found
body: <p>I dont' know why I cannot install ruby through yum in my RHEL6.2
  How can I fix it. I don't wanna install through source. Any idea?</p>
  
  <pre><code>[root@kithost ~]# yum install ruby
  Loaded plugins: product-id, refresh-packagekit, security, subscription-manager
  Updating certificate-based repositories.
  Setting up Install Process
  No package ruby available.
  Error: Nothing to do
  </code></pre>
  
  <p>RVM is a solution but it is not that I want.</p>
  
  <p>What I want to know is that once we can't find any package from yum, what kind of thing should we fix into order to let yum find it?</p>
