title: Why do I get "this perl hasn't been configured and built properly for the threads module to work"?
body: <p>I am not a Perl programmer. I was just asked to install a Perl program and followed only the instruction given to me. And I got the following error:</p>
  
  <blockquote>
    <p>This <code>perl</code> hasn't been configured and built properly for the threads
    module to work.  (The 'useithreads' configuration option hasn't been
    used.)</p>
    
    <p>Having threads support requires all of Perl and all of the XS modules
    in the Perl installation to be rebuilt, it is not just a question of
    adding the threads module.  (In other words, threaded and non-threaded
    Perls are binary incompatible.)</p>
    
    <p>If you want to the use the threads module, please contact the people
    who built your Perl.</p>

  <p>How to do I fix this error? I am using hostgator dedicated server - Linux.</p>
