  <p>I run this:</p>
  
  <p><code>gem install ruby-debug19</code></p>
  
  <p>And in my cucumber <code>env.rb</code> file, I have this:</p>
  
  <p><code>require 'ruby-debug'</code></p>
  
  <p>When I try to run, though, I get this exception:</p>
  
  <p><code>/home/skendall/.rvm/gems/ruby-1.9.3-p0/gems/ruby-debug-base19-0.11.25/lib/ruby_debug.so: undefined symbol: ruby_current_thread - /home/skendall/.rvm/gems/ruby-1.9.3-p0/gems/ruby-debug-base19-0.11.25/lib/ruby_debug.so (LoadError)</code></p>
  
  <p>What do I need to do to get ruby-debug to work with 1.9.3-p0?</p>
