When I try to run "rails server" on a new project it returns
Could not find gem 'mysql2 (>= 0) X86-mingw32' in any of the gem sources listed in your Gemfile.
Run 'bundle install' to install missing gems.
I ran into this issue a while back setting up a RoR dev environment on a windows machine. Had to copy the dll to the ruby/bin folder. See the thread from ruby-forum... http://www.ruby-forum.com/topic/150580
