title: permission denied error when I run make install to get setup with doxygen
body: <p>I am following the <a href="http://www.doxygen.nl/download.html#gitrepos" rel="nofollow noreferrer">steps</a> from the doxygen online documentation to get doxygen up and running on OS X 10.7.5. I successfully cloned the repo, ran <code>./configure</code> and <code>make</code> and then skipped the part that said <code>make distclean</code>. When I try to run <code>make install</code>  I get the following error: </p>
  
  <pre><code>akh2103: make install
  /usr/bin/install -d //usr/local/bin
  install: chmod 755 //usr/local/bin: Operation not permitted
  /usr/bin/install -m 755 bin/doxygen        //usr/local/bin
  install: //usr/local/bin/doxygen: Permission denied
  make: *** [install] Error 71
  </code></pre>

  <li>I am new to linux/open source development (from .NET) and I'm assuming that making (creating the binary) is different from installing the built code. So I am assuming that I need to run <code>make install</code> even if I am not running the <code>make distclean</code> commands</li>
  <li>Assuming I need to run <code>make install</code> how do I go about debugging/getting around this error.</li>
