Hello-

This is a potentially obvious problem. I’m trying to generate a uuid in  
one of my models. I poked around and found the uuidtools gem (is there a  
better way to generate a uuid?). Here’s the code I’m currently using:

require ‘rubygems’  
require ‘uuidtools’

class Subscription \< ActiveRecord::Base

def initialize  
self.guid UUID.timestamp\_create.to\_s  
end  
end

It seems straight-forward, but I keep getting this error:

“no such file to load – uuidtools”

I installed the gem previously using “gem install uuidtools” and it  
seemed to be successful. What am I missing?

Regards-  
Eric
