title: Unable to install chef-server older version on centos manually
body: <p>I am on Centos 6.5 and would like to have chef-server version 10.30.4 as <a href="http://rubygems.org/gems/chef-server" rel="nofollow">here</a>. </p>
  
  <p>I am using the ruby version of 1.9.3 via RVM. As on this <a href="http://tecadmin.net/install-ruby-1-9-3-or-multiple-ruby-verson-on-centos-6-3-using-rvm" rel="nofollow">link</a>.</p>
  
  <p>and even after having installed all dependencies as on <a href="https://wiki.opscode.com/display/chef10/Installing+Chef+Server+Manually" rel="nofollow">this page</a></p>
  
  <p>like </p>
  
  <ul>
  <li>CouchDB,  RabbitMQ,  Java,  GEOS,  zlib and libxml,  setting up the
  GPG key  and also tried the hammer method of yum groupinstall
  "Development Tools"</li>
  </ul>
  
  <p>but getting the following errors on</p>
  
  <pre><code>gem install chef-server -v "10.30." 
  </code></pre>
  
  <p>Note: all of these are being done as root. </p>
  
  <p>Error is </p>
  
  <blockquote>
    <p>ERROR:  While executing gem ... (Gem::RemoteFetcher::UnknownHostError)
        no such name (<a href="https://api.rubygems.org/api/v1/dependencies?gems=mixlib-authentication" rel="nofollow">https://api.rubygems.org/api/v1/dependencies?gems=mixlib-authentication</a>)</p>
  </blockquote>
  
  <p>And by the way gem source rightly points</p>
  
  <p>gem source
  <strong>* CURRENT SOURCES *</strong></p>
  
  <p><a href="https://rubygems.org/" rel="nofollow">https://rubygems.org/</a></p>
  
  <p>There seems to have been some progress after I did </p>
  
  <pre><code>gem update
  </code></pre>
  
  <p>And now the error is </p>
  
  <blockquote>
    <p>ERROR:  Error installing chef-server:     ERROR: Failed to build gem
    native extension.</p>
  
  <pre><code>/usr/local/rvm/rubies/ruby-1.9.3-p545/bin/ruby extconf.rb checking for main() in -lgecodesearch... no
