Subject: GEM's on Ubuntu

Hi, i know that the post is old, but i'm having the same problem, i am running Ubuntu 10.04 and installed

ruby1.9.1-full
rubygems1.9.1

when requiring active record for example:

require 'rubygems'
require 'active_record'

and run the file i get error:
`require': no such file to load -- active_record (LoadError)

I dont have any other versions of ruby, just 1.9.1, any ideas?

Thanks in advanced
