[chef] Installing Gems

[< >]

So I am trying to install a gem via Chef like so (just like their doc says),

cookbook_file "#{Chef::Config[:file_cache_path]}/pony.gem" do
  source "pony.gem"
  backup false
  mode "0755"
end

gem_package "pony" do
  action :install
  source "#{Chef::Config[:file_cache_path]}/pony.gem"
end

But when I run chef-client I get this,

NOTE: Gem.source_index is deprecated, use Specification. It will be removed on
or after 2011-11-01.
Gem.source_index called from
/usr/lib64/ruby/gems/1.8/gems/chef-0.10.2/bin/../lib/chef/provider/package/rubygems.rb:202.
NOTE: Gem::SourceIndex#search is deprecated with no replacement. It will be
removed on or after 2011-11-01.
Gem::SourceIndex#search called from
/usr/lib64/ruby/gems/1.8/gems/chef-0.10.2/bin/../lib/chef/provider/package/rubygems.rb:76.

Running to irb and doing a quick require says that it can't find the gem
either.
