This error occurs because libopenssl-ruby is not installed.

Kokko @ kokko-laptop :~ /Cookbook $ sudo apt-cache search libopenssl-ruby
Libopenssl-ruby-OpenSSL interface for Ruby
Libopenssl-ruby1.9-OpenSSL interface for Ruby 1.9
Ruby1.8-Interpreter of object-oriented scripting language Ruby 1.8
Libopenssl-ruby1.8-OpenSSL interface for Ruby 1.8

Here we use ruby1.8, run sudo apt-get install libopenssl-ruby1.8.
