title: How to build pgmagick on linux (CentOS)?
body: <p>I'm not having much success when attempting building <code>pgmagick</code> on CentOS 5.6.</p>
  
  <p>I've installed the following via <code>yum</code>:</p>
  
  <pre><code>boost-1.33.1
  boost-devel-1.33.1
  GraphicsMagick-1.3.14
  GraphicsMagick-c++-1.3.14
  GraphicsMagick-devel-1.3.14
  GraphicsMagick-c++-devel-1.3.14
  python-2.6.5
  python-devel-2.6.5
  </code></pre>
  
  <p>However, whenever I try to build <code>pgmagick</code> I get the following error:</p>
  
  <pre><code>/usr/include/boost/python/converter/registered.hpp: In instantiation of ‘const boost::python::converter::registration&amp; boost::python::converter::detail::registered_base&lt;const volatile void&gt;::converters’:

  </code></pre>
  
  <p>I've also tried installing <code>boost141</code>, <code>boost141-devel</code> and <code>boost141-python</code> but pgmagick won't build against those libraries.</p>
  
  <p>Any suggestions on how I can fix the problem, or further diagnose the issue?</p>
