title: Why do I get the warning "epstool binary is not available", with saveas(gcf,'filename.pdf')
body: <p>I am plotting contours with octave and with the command <code>saveas(gcf,'rainzam.pdf')</code> I get the output ok, but I was just wondering why I get the following warnings:</p>
  
  <pre><code>warning: print.m: epstool binary is not available.
  Some output formats are not available.
  warning: print.m: fig2dev binary is not available.
  Some output formats are not available.
  </code></pre>
  
  <p>This is not serious but if there is a way of making them disappear, I would appreciate assistance.</p>
