"/home/nasir/.rvm/gems/ruby-1.9.2-p320@rails328/gems/constant-contact-ruby-0.2.5/lib/constant_contact/contact_list.rb:21:in instance_eval'", "/home/nasir/.rvm/gems/ruby-1.9.2-p320@rails328/gems/constant-contact-ruby-0.2.5/lib/constant_contact/contact_list.rb:21:inblock in initialize'", "/home/nasir/.rvm/gems/ruby-1.9.2-p320@rails328/gems/constant-contact-ruby-0.2.5/lib/constant_contact/contact_list.rb:12:in each'", "/home/nasir/.rvm/gems/ruby-1.9.2-p320@rails328/gems/constant-contact-ruby-0.2.5/lib/constant_contact/contact_list.rb:12:ininitialize'", "/home/nasir/.rvm/gems/ruby-1.9.2-p320@rails328/gems/constant-contact-ruby-0.2.5/lib/constant_contact/contact_list.rb:55:in new'", "/home/nasir/.rvm/gems/ruby-1.9.2-p320@rails328/gems/constant-contact-ruby-0.2.5/lib/constant_contact/contact_list.rb:55:inblock in all'", "/home/nasir/.rvm/gems/ruby-1.9.2-p320@rails328/gems/constant-contact-ruby-0.2.5/lib/constant_contact/contact_list.rb:54:in each'", "/home/nasir/.rvm/gems/ruby-1.9.2-p320@rails328/gems/constant-contact-ruby-0.2.5/lib/constant_contact/contact_list.rb:54:inall'"

Is it the problem only with me or its still need to fix?

I am using rails3.2.8 and rvm.

The library hardcodes someones API_KEY. My understanding is that each client application should use their own API_KEY. This should be part of the authentication information used to initialize the library. A simple change would be to include an api_key argument to the setup method. You could default to the one in the code, but it seems like a bad idea to have one hard coded in the library.
