title: Error aroused when installing pymol on CentOS 7 from source
body: <p>I am trying to intall pymol on my centos 7 system from source using the mothed discribed at pymolwiki (<a href="https://pymolwiki.org/index.php/Linux_Install" rel="nofollow noreferrer">https://pymolwiki.org/index.php/Linux_Install</a>)
  Everything was ok until I run install script: </p>
  
  <pre><code>#!/bin/bash -e
  
  prefix=/opt/pymol-svn
  modules=$prefix/modules
  
  # If you want to install as root, then split this line up in "build"
  # and "install" and run the "install" with "sudo"
  python2.7 setup.py build install \
      --home=$prefix \
      --install-lib=$modules \
      --install-scripts=$prefix
  </code></pre>
  
  <p>I got a error message and the installation process was terminated:</p>
  
  <p>In file included from contrib/mmtf-c/mmtf_parser.cpp:31:0:
  contrib/mmtf-c/mmtf_parser_private.h:38:23: fatal error: msgpack.hpp: No such file or directory
   #include 
                         ^
  compilation terminated.</p>
  
  <p>I then installed msgpack by yum command and tried to run the pymol install script again, but the same error still occurred.</p>
  
  <p>I googled this problem but cannot find a answer. Could anyone help me here?</p>
  
  <p>Best regards.</p>
