First - is there a section on this forum or another forum for Newbies. I don't want to interfere with the pros. I'm trying to load and run the depot_v sample cod from the Rapid book. Here is my console: C:\Sites\depot_v>bundle install Fetching source index for http://rubygems.org/ Using rake (0.9.2.2) Using multi_json (1.0.3) Using activesupport (3.1.0) Using bcrypt-ruby (3.0.1) Using builder (3.0.0) Using i18n (0.6.0) Using activemodel (3.1.0) Using erubis (2.7.0) Using rack (1.3.5) Using rack-cache (1.0.3) Using rack-mount (0.8.3) Using rack-test (0.6.1) Using hike (1.2.1) Using tilt (1.3.3) Using sprockets (2.0.3) Using actionpack (3.1.0) Using mime-types (1.17.2) Using polyglot (0.3.3) Using treetop (1.4.10) Using mail (2.3.0) Using actionmailer (3.1.0) Using active_utils (1.0.1) Using braintree (2.13.1) Using json (1.6.1) Using money (3.7.1) Using activemerchant (1.20.0) Using arel (2.2.1) Using tzinfo (0.3.31) Using activerecord (3.1.0) Using activeresource (3.1.0) Using ansi (1.4.1) Using bundler (1.0.21) Using highline (1.6.8) Using net-ssh (2.2.1) Using net-scp (1.0.4) Using net-sftp (2.0.5) Using net-ssh-gateway (1.1.0) Using capistrano (2.9.0) Using coffee-script-source (1.1.3) Using execjs (1.2.9) Using coffee-script (2.2.0) Using rack-ssl (1.3.2) Using rdoc (3.11) Using thor (0.14.6) Using railties (3.1.0) Using coffee-rails (3.1.1) Using haml (3.1.3) Using jquery-rails (1.0.18) Installing mysql2 (0.3.10) with native extensions Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension .
