title: Brew doctor says: "Warning: /usr/local/include isn't writable."
body: <p>Brew doctor says: </p>
  
  <blockquote>
    <p>Warning: /usr/local/include isn't writable. This can happen if you "sudo make install" software that isn't managed by Homebrew.</p>
    
    <p>If a brew tries to write a header file to this directory, the install
    will fail during the link step.</p>
    
    <p>You should probably <code>chown</code> /usr/local/include</p>
  </blockquote>
  
  <p>I've tried different commands to solve this but I'm still stuck here.</p>
  
  <p>I'm running homebrew on 10.8.2</p>
