title: Syntax highlighting within #+begin_src block in emacs orgmode not working
body: <p>I have tried many different languages and copied various examples, but none of my code blocks within orgmode get syntax highlighting. Here is what I'm trying:</p>
  
  <pre><code>#+begin_src python
  
  def main():
    print "Hello %s" % ("what's the problem")
  
  #+end_src
  
  #+begin_src c++
  
  for (int i = 0; i &lt; 30; i++) 
  {
    cout &lt;&lt; "Hello" &lt;&lt; endl;
  }
  
  #+end_src
  </code></pre>
  
  <p>When exported to HTML, it shows up in a source code block, but with no highlighting there either.</p>
  
  <p>I am using the newest org (7.8.10). Am I missing something here?</p>
