title: Can't run "ruby -v" after install
body: <p>I followed <a href="http://www.rosehosting.com/blog/install-ruby-on-rails-with-apache-and-passenger-on-centos-6/" rel="nofollow">this guide</a> to install <code>Ruby</code> on <code>Centos 6.5</code> with <code>Mod Passenger</code> and <code>Apache</code>. But after running the command: <code># curl -L https://get.rvm.io | bash -s stable --ruby</code> and then running <code>ruby -v</code> in the console,  I got this message </p>
  
  <p><code>-bash: ruby: command not found</code></p>
  
  <p>what am I doing wrong? Can any one share a good guide or tutorial to get this working? I need to create a <code>ROR</code> application to start programming on this.</p>
