title: make install generates file exists error
body: <p>I am trying to compile and create an executable of this <a href="https://github.com/scribd/advancecomp/tree/master/src" rel="nofollow">tool</a>, did a ./configure and then make and then make install, however during the process I got this error:</p>
  
  <pre><code>test -z "/usr/local/bin" || ./install-sh -c -d "/usr/local/bin"
  mkdir: /usr/local/bin: File exists
  make[1]: *** [install-binPROGRAMS] Error 1
  make: *** [install-am] Error 2
  </code></pre>
  
  <p>Any idea on how to get around this?</p>
