Gmail Automation with Ruby and Mechanize

Found a post online and figured I'd try to do this myself. Works surprisingly well when each line is pasted into irb or when using rails script/runner,
but it appears as though google is somehow blocking straight up 'ruby gmail.rb' calls.


gmail.rb:

    1 require 'rubygems'
    2 require 'mechanize'
    3 
    4 agent = WWW::Mechanize.new 
    5 agent.user_agent_alias = 'Linux Mozilla'
    6 page = agent.get 'http://www.gmail.com'
    7 
    8 
    9 
   10 # #log into gmail
   11 form = page.forms.first
   12 form.Email = 'user.name'
   13 form.Passwd = 'password'
   14 page = agent.submit(form, form.buttons.first)
   15 
   16 
   17 # switch to basic view
   18 page = agent.get page.search("//meta").first.attributes['href'].to_s.gsub(/'/,'')
   19 page = agent.get page.uri.to_s.sub(/\?.*$/, "?ui=html&zy=n")
   20 
   21 
   22 #create and send the email.
   23 page = agent.click page.links.find { |l| l.text =~ /compose/i }
   24 
   25 form = page.forms[1]
   26 form.to = 'someone.else@gmail.com'
   27 
   28 form.subject = 'test subject'
   29 sleep 3
   30 form.body = <<EOF
   31 "Hi,
   32 
   33 I would like to spam you using ruby mechanize and gmail.
   34 
   35 "
   36 EOF
   37 page = agent.submit(form, form.buttons.first)
   38
