I use MacPorts to manage Ruby / Rails / Gems installations. Recently, after execution gem install wirble, wirble does not load when I start the irb instance. Here's the conclusion:
$ irb
Couldn't load Wirble: no such file to load
Wirble gem does not appear in my $ LOAD_PATH:

Gemstone is definitely installed:
$ gem list |grep -i wirble
wirble (0.1.3)
It is located in /opt/local/lib/ruby/gems/1.9.1/gems/wirble-0.1.3/
How do I get this and future gems that I set to my $ LOAD_PATH?
