how to use Ruby libraries with Ironruby

Question

I would like to use traditional Ruby libraries (1.8.6) with Ironruby. I'm having problems. For instance, "require 'thread'" doesn't seem to work in an Ironruby script. Do I need to put the ruby libraries in the Ironruby lib folder?

IronRuby use igem, you can use igem ENV to inspect where are the gems, and install the missing one using igem install.
