Ruby Gem Activate Problem n NetBeans

I have been programming Java in NetBeans for a long while, but I just bought the book “Using JRuby” (really well-written) and came to the point where the example in the book needed the gem Rubeus. I downloaded it, went to Tools/Ruby Gems in NetBeans, and managed to get it installed (or so it appeared) successfully. Then I tried to run the example code, but I get the message
/jruby1.6/lib/ruby/site_ruby/1.8/rubygems.rb:812:in `report_activate_error’: Could not find RubyGem activesupport (= 2.1.2) (Gem::LoadError)
So apparently a gem needs to be activated, even after it’s installed. How do I do that?
Thanks in advance for any help.
