Subject: gems, helpers and rails

Hi i'm trying to get the paypal library working in my rails app. I know 
this is the ruby forum but i think this might be half a ruby question. I 
installed the paypal gem.

$ gem list

*** LOCAL GEMS ***

##rails ones + others##

money (1.7.1)
    Class aiding in the handling of Money.

paypal (2.0.0)
    Paypal IPN integration library for rails and other web applications
#############

irb(main):001:0> require 'rubygems'
=> true
irb(main):002:0> require 'paypal'
=> false
irb(main):003:0> include Paypal
NameError: uninitialized constant Paypal
        from (irb):3
irb(main):004:0> include paypal
NameError: undefined local variable or method `paypal' for 
#<Object:0xb7cdd970>
        from (irb):4

when i try and use the form helpers in rails
specifically the code below taken from the RDoc:

 <%= paypal_form_tag %>
25:      <%= paypal_setup "Item 500", Money.us_dollar(50000), 
"bob@bigbusiness.com", :notify_url => url_for(:only_path => false, 
:action => 'paypal_ipn') %>

 if get this error:
undefined local variable or method `paypal_form_tag' for 
#<#<Class:0xb7692568>:0xb7692540>

Extracted source (around line #24):

21:   </tr>
22: </table>
23:
24:    <%= paypal_form_tag %>

I have added require 'paypal' to the end of my enviroment.rb .
I have this as my application_helper.rb

require 'paypal'
module ApplicationHelper
	include Paypal::Helpers
end


I also now get this in my log

ApplicationController: missing default helper path application_helper

Please give me something else to try.
I am stumped!
regards
c
