I've made some more changes, it seems I am back to the origin again, I 
am getting form_remote_tag NoMethodError again in httpd error_log...I 
don't know what I am doing wrong. Can someone provide/point me to a 
simple test case that actually works with apache2?

<% require 'rubygems' %>
<% gem 'actionpack' %>
<!--% gem 'activesupport' %-->
<!--% require 'active_support' %-->
<% require 'action_controller' %>
<% require 'action_view' %>
<% require 'action_pack' %>
<% require 'action_view/helpers/prototype_helper' %>
<% include ActionView::Helpers::PrototypeHelper %>
<% include ActionView::Helpers::JavaScriptHelper %>
<% include ActionView::Helpers::UrlHelper %>
<!--% require 'action_view/helpers/javascripts/prototype.js' %-->

<%= form_remote_tag :url => { :action => 'whet' } %>
Enter your name: <%= text_field_tag :name %>
<%= submit_tag "Greet Me" %>
<%= end_form_tag %>
<h2 id="greeting" style="display: none"></h2>
