title: Sublime Text: Permission denied when running Sublime REPL by non-root user under Ubuntu
body: <p>When trying to run <a href="https://github.com/wuub/SublimeREPL">Sublime REPL</a>, I get a message box with <em>permission denied</em> error: <code>IOError(13, 'Permission denied')</code> unless I launch Sublime Text with root privileges (<code>sudo sublime</code>). It holds for any REPL language.</p>
  
  <p>I'm using Ubuntu 12.10, and Sublime resides in <code>/opt/</code> directory.</p>
  
  <p>Since I can't google anyone else having this problem, probably there's something special about my filesystem privileges somewhere. What can cause files that Sublime REPL use be protected?</p>
