title: yet another unknown terminal type
body: <p>From Ubuntu, I open <code>gnome-terminal</code>, and ssh to a <code>OS X</code>.</p>
  
  <p><code>OS X</code> version is:</p>
  
  <pre><code>$ sw_vers
  ProductName:    Mac OS X
  ProductVersion: 10.9.5
  BuildVersion:   13F34
  </code></pre>
  
  <p>I have for example the file <code>xterm-256color</code>:</p>
  
  <pre><code>$ ls /usr/share/terminfo/78/xterm-256color
  /usr/share/terminfo/78/xterm-256color
  </code></pre>
  
  <p>But I can't do a simple <code>clear</code>:</p>
  
  <pre><code>$ TERM='xterm-256color' clear
  'xterm-256color': unknown terminal type.
  </code></pre>
