Dependency Issue with Gemfiles and Webrick

I've been trying to configure webrick to use SSL on all pages of my application.

I added

gem 'rack-ssl', :require => 'rack/ssl'
 

to my gem file and

config.middleware.insert_before ActionDispatch::Static, "Rack::SSL"
 config.force_ssl = true
 

to my /config/application.rb file. And I configured webrick to use my self signed certificate by modifying my /script/rails file to looke like so

require 'rubygems'
 require 'rails/commands/server'
 require 'rack'
 require 'webrick'
 require 'webrick/https'
 
 module Rails
   class Server < ::Rack::Server
     def default_options
       super.merge({
           :Port => 3001,
           :environment => (ENV['RAILS_ENV'] || "development").dup,
           :daemonize => false,
           :debugger => false,
           #:pid => File.expand_path("tmp/pids/server.pid"),
           :config => File.expand_path("config.ru"),
           :SSLEnable => true,
           :SSLVerifyClient => OpenSSL::SSL::VERIFY_PEER,
           :SSLPrivateKey => OpenSSL::PKey::RSA.new( File.open("home/sureweb/rubystuff/server.cert.key").read),
       :SSLCertificate => OpenSSL::X509::Certificate.new(File.open("home/sureweb/rubystuff/server.cert.crt").read),
           :SSLCACertificateFile => 'home/sureweb/rubystuff/server.crt',
           :SSLCertName => [["CN", WEBrick::Utils::getservername]]
      })
     end
   end
 end
 
 APP_PATH = File.expand_path('../../config/application',  __FILE__)
 require File.expand_path('../../config/boot',  __FILE__)
 require 'rails/commands'
 

But every time I run rails s I get a message saying

You have already activated activesupport 3.2.3, but your Gemfile requires activesupport 3.0.12. Using bundle exec may solve this. (Gem::LoadError)
 

Normally I could solve this by removing the version 3.2.3 but I have numerous other gems that depend on it so that is not an option. Is there another way to get this working?
