title: How to install current OpenPYXL package on Ubuntu
body: <p>I have some spreadsheet reading code (using openpyxl) that works correctly on my Windows installation.  On my Ubuntu Rackspace server, however, it fails with a named range error.</p>
  
  <p>I notice that the openpyxl package on Ubuntu (which I installed last week using apt-get) is several years old (1.5.6).  I'd like to install the newest version (1.6.2).</p>
  
  <p>What tool can I use to install the newer version, or is it something I need to do manually?</p>
