Get the sample application working
   notes: put instant rails somewhere with a short directory name-- like C:/ruby
     default windows unzip had trouble, 7zip worked; this is documented on instant rails site.

Unzip wagn into rails_apps directory

Open an explorer window to the wagn directory.
  copy sample_database.yml  to database.yml
  Edit config/database.yml and change these settings:
     adapter: mysql
     user: root

  Edit db/migrate/001_jump_to_version_109
    change line 167 from
      `rake wagn:load_bootstrap_data`
       to
      Rake::Task['wagn:load_bootstrap_data'].invoke

Open a command prompt:
   In dialogue under: I-icon -> RailsApplications->Manage Rails Applications.
   click 'Create new rails app' -- this opens a command prompt in rails_apps with proper path etc.

At the command prompt:
  gem install json_pure
  gem install ruby_openid
  gem install cached_model
  rake db:create
  rake db:migrate

Now you can 'Start with mongrel' from the RailsApplications dialogue.
