Capistrano recipes to make it easier to specify gems that need to be installed.

• Capistrano 2

$ gem install eric-gemist -s http://gems.github.com/

Load the gem in your capistrano config/deploy.rb:

gem 'eric-gemist'
require 'gemist'

Then configure the gems that should be installed for each role:

gemist.role :app, %w(hpricot stomp mongrel mongrel_cluster xmpp4r)
gemist.role :stompserver, 'stompserver'
gemist.role :app, 'eric-god',  :version => '>= 0.7.7', :source => 'http://gems.github.com/'

To update the rubygems on your systems, you can run:

$ cap gems:update_system

To install all the required gems, just run:

$ cap gems:install

If you are like me and have set :use_sudo to false, you can make sure sudo is used to install the gems by running:

$ cap gems:install -s run_method=sudo

Special thanks to:
