[chef] Re: Re: Re: How to add ruby lib as depend at LWRP

Hey
plain ruby code is executed at Compile time, not at converge time, so
the timing is right. That said, I've only done similar in a recipe
context, but i think the following code should do what you need:

 run_context = Chef::RunContext.new(node, {})
 p =  Chef::Resource::AptPackage.new("libsqlite3-ruby", run_context)
 p.run_action(:install)
