eruby & Mechanize error

Hi,

I am working on a web tool that takes user input and submits this
information to a list of websites like google, yahoo, hotmail etc. It
automates form (e.g login form) submission for these websites using
Mechanize in Ruby.
I have used eruby for the web pages, but when I try to use Mechanize,
the
web page gives error "Temporary failure in name resolution"

<%
require 'rubygems'
require 'mechanize'

agent = WWW::Mechanize.new
page = agent.get(http://www....)
form = page.forms[0]
google_form.q = 'ruby mechanize'
page = agent.submit(form)
puts page.body
%>

However if I run the same script from command line, it works fine.

Does somebody know how can I make this work from the web page ?
