title: So much dependencies for installing the package 'nmap'
body: <p>I want to install the package <code>nmap</code> on debian by the command <code>apt-get</code>, but It seems that the package <code>nmap</code> depends on so many dependencies! For example It depends on the packages <code>imagemagick</code> and <code>x11-common</code>! Unless <code>nmap</code> needs the X window system !? Is everything OK?</p>
  
  <pre><code># apt-get install nmap
