title: no such file to load -- ffi_c (LoadError)
body: <p>This problem is bugging me for a couple of days now... Whenever I'm using the .bring_to_front method</p>
  
  <pre><code>require "rubygems"
  require "watir"
  
  browser = Watir::Browser::new
  browser.bring_to_front
  </code></pre>
  
  <p>I get this error:</p>
  
  <pre><code>(...)rubygems/custom_require.rb:36:in `require': no such file to load -- ffi_c (LoadError)
  </code></pre>
  
  <p>I tried uninstalling and reinstalling ffi/watir/ruby/netbeans without success.</p>
  
  <p>line 36 is in custom_require.rb</p>
  
  <pre><code>def require path
  if Gem.unresolved_deps.empty? or Gem.loaded_path? path then
    gem_original_require path
  else
    spec = Gem.searcher.find_active path
    unless spec then
      found_specs = Gem.searcher.find_in_unresolved path
      unless found_specs.empty? then
        found_specs = [found_specs.last]
      else
        found_specs = Gem.searcher.find_in_unresolved_tree path
      end
      found_specs.each do |found_spec|
        Gem.activate_spec found_spec
      end
    end
    return gem_original_require path #problem
