title: RVM doesn't get installed
body: <p>I'm trying to install RVM in Ubuntu 11.04.
  When I give command :</p>
  
  <pre><code>bash &lt; &lt;( curl https://rvm.io/releases/rvm-install-head )
  </code></pre>
  
  <p>I get error :</p>
  
  <pre><code>bash: line 2: syntax error near unexpected token `&lt;'
  </code></pre>
  
  <p>I tried doing this  - </p>
  
  <pre><code>bash &lt; &lt;( curl -s https://rvm.io/releases/rvm-install-head )
  </code></pre>
  
  <p>but this gives me error - </p>
  
  <pre><code>curl: (1) Protocol https not supported or disabled in libcurl
  </code></pre>
  
  <p>On giving this command : </p>
  
  <pre><code>bash &lt; &lt;(curl -s https://rvm.io/install/rvm)
  </code></pre>
  
  <p>does not produce any errors and does not install or download anything.</p>
  
  <p>What am I missing ??</p>
