  <p>The problem is in OpenGL or SDL.
  I do not have SDL.h at /usr/local/SDL/SDL.h, so gcc cannot find it.</p>
  
  <p>I have SDL.h installed by MacPorts at /opt/local/include/SDL/SDL.h.</p>
  
  <p>I tried to copy it to /Masi/local/SDL/SDL.h unsuccessfully at the folder  by</p>
  
  <pre><code>cp /opt/local/include/SDL/SDL.h /
  </code></pre>
  
  <p>and by </p>
  
  <pre><code>cp /opt/local/include/SDL/SDL.h /Masi/local/SDL/
  </code></pre>
  
  <p>I tried to solve the problem by creationg a symlink by</p>
  
  <pre><code>$ln -s /opt/local/include/SDL/SDL.h /Masi/local/SDL/SDL.h
  </code></pre>
