Capifony database functions fail with `require': cannot load such file -- FileUtils (LoadError)

When I call any of the Capifony database functions, `cap database:move:to_remote` for example, I get the following ruby error: ``` jeremykendall@isr-thinkpad-420s:~/dev/sites/app$ cap develop database:move:to_remote triggering load callbacks * executing `develop' triggering start callbacks for `database:move:to_remote' * executing `multistage:ensure' * executing `database:move:to_remote' * executing `database:dump:local' /home/jeremykendall/.rvm/rubies/ruby-1.9.3-p125/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- FileUtils (LoadError) from /home/jeremykendall/.rvm/rubies/ruby-1.9.3-p125/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require' from /home/jeremykendall/.rvm/gems/ruby-1.9.3-p125@interperf/gems/capifony-2.1.5/lib/symfony2.rb:101:in `block (3 levels) in load' from /home/jeremykendall/.rvm/gems/ruby-1.9.3-p125@interperf/gems/capistrano-2.11.2/lib/capistrano/configuration/execution.rb:139:in `instance_eval' from /home/jeremykendall/.rvm/gems/ruby-1.9.3-p125@interperf/gems/capistrano-2.11.2/lib/capistrano/configuration/execution.rb:139:in `invoke_task_directly' from /home/jeremykendall/.rvm/gems/ruby-1.9.3-p125@interperf/gems/capistrano-2.11.2/lib/capistrano/configuration/callbacks.rb:25:in `invoke_task_directly_with_callbacks' from /home/jeremykendall/.rvm/gems/ruby-1.9.3-p125@interperf/gems/capistrano-2.11.2/lib/capistrano/configuration/execution.rb:89:in `execute_task' from /home/jeremykendall/.rvm/gems/ruby-1.9.3-p125@interperf/gems/capistrano-2.11.2/lib/capistrano/configuration/namespaces.rb:191:in `method_missing' from /home/jeremykendall/.rvm/gems/ruby-1.9.3-p125@interperf/gems/capistrano-2.11.2/lib/capistrano/configuration/namespaces.rb:191:in `method_missing' from /home/jeremykendall/.rvm/gems/ruby-1.9.3-p125@interperf/gems/capistrano-2.11.2/lib/capistrano/configuration/namespaces.rb:110:in `block in define_task' from /home/jeremykendall/.rvm/gems/ruby-1.9.3-p125@interperf/gems/capifony-2.1.5/lib/symfony2.rb:159:in `block (3 levels) in load' from /home/jeremykendall/.rvm/gems/ruby-1.9.3-p125@interperf/gems/capistrano-2.11.2/lib/capistrano/configuration/execution.rb:139:in `instance_eval' from /home/jeremykendall/.rvm/gems/ruby-1.9.3-p125@interperf/gems/capistrano-2.11.2/lib/capistrano/configuration/execution.rb:139:in `invoke_task_directly' from /home/jeremykendall/.rvm/gems/ruby-1.9.3-p125@interperf/gems/capistrano-2.11.2/lib/capistrano/configuration/callbacks.rb:25:in `invoke_task_directly_with_callbacks' from /home/jeremykendall/.rvm/gems/ruby-1.9.3-p125@interperf/gems/capistrano-2.11.2/lib/capistrano/configuration/execution.rb:89:in `execute_task' from /home/jeremykendall/.rvm/gems/ruby-1.9.3-p125@interperf/gems/capistrano-2.11.2/lib/capistrano/configuration/execution.rb:101:in `find_and_execute_task' from /home/jeremykendall/.rvm/gems/ruby-1.9.3-p125@interperf/gems/capistrano-2.11.2/lib/capistrano/cli/execute.rb:46:in `block in execute_requested_actions' from /home/jeremykendall/.rvm/gems/ruby-1.9.3-p125@interperf/gems/capistrano-2.11.2/lib/capistrano/cli/execute.rb:45:in `each' from /home/jeremykendall/.rvm/gems/ruby-1.9.3-p125@interperf/gems/capistrano-2.11.2/lib/capistrano/cli/execute.rb:45:in `execute_requested_actions' from /home/jeremykendall/.rvm/gems/ruby-1.9.3-p125@interperf/gems/capistrano-2.11.2/lib/capistrano/cli/help.rb:19:in `execute_requested_actions_with_help' from /home/jeremykendall/.rvm/gems/ruby-1.9.3-p125@interperf/gems/capistrano-2.11.2/lib/capistrano/cli/execute.rb:34:in `execute!' from /home/jeremykendall/.rvm/gems/ruby-1.9.3-p125@interperf/gems/capistrano-2.11.2/lib/capistrano/cli/execute.rb:14:in `execute' from /home/jeremykendall/.rvm/gems/ruby-1.9.3-p125@interperf/gems/capistrano-2.11.2/bin/cap:4:in `<top (required)>' from /home/jeremykendall/.rvm/gems/ruby-1.9.3-p125@interperf/bin/cap:19:in `load' from /home/jeremykendall/.rvm/gems/ruby-1.9.3-p125@interperf/bin/cap:19:in `<main>' ``` My deploy.rb: ``` set :stage_dir, 'app/config/deploy' require 'capistrano/ext/multistage' set :stages, %w{production testing develop} default_run_options[:pty] = true set :application, "appname" set :deploy_to, "/home/isr/sites/app" set :deploy_via, :remote_cache set :scm, :git set :repository, "git@github.com:jeremykendall/redacted.git" set :user, "isr" set :use_sudo, false ssh_options[:forward_agent] = true set :model_manager, "doctrine" set :keep_releases, 3 set :update_vendors, true set :shared_files, ["app/config/parameters.yml", "app/config/parameters.ini"] set :shared_children, [app_path + "/logs", app_path + "/cache", web_path + "/uploads", "vendor"] ``` My app/config/deploy/develop.rb ``` #
