title: Getting rid of "git: /usr/local/lib/libz.so.1: no version information available (required by git)"
body: <p>For every git command I try to run, I get this message. Example:</p>
  
  <pre><code>stewie:~# git --version
  git: /usr/local/lib/libz.so.1: no version information available (required by git)
  git version 1.7.11.4
  </code></pre>
  
  <p>How can I get rid of this?</p>

  <p>I'm on Debian Lenny (5), so, unfortunately, using <code>apt-get</code> isn't that easy.</p>
