Dynamic URLs in CMS

Use RVM:
sudo gem install rvm
keeps separate ruby installs each with independent gem homes.
Install Ruby 1.8.6, Ruby 1.8.7, Ruby 1.9, and REE

users can choose layouts dynamically based on a file sys scrape of available layouts in layouts directory.
map.page '/*permalink', :controller => 'site', :action => 'cms', :permalink => nil # the nil provides a default

in SiteController:
#When rendering 404 error page always set :status => 404
def cms
@permalink = params[:permalink].join('/')
#determines what other action needs to be called / rendered
end
