I've tried following the directions listed here, but it seems damn near everything in the ruby/rails community is NOT designed with windows in mind. Had to install MINGW32 and MSYS to even get native gems to compile. Had to install the Git Bash as the templates that are run assume you've got git functioning on your system. Depending on which environment I try this in (cygwin vs the git bash) I'm getting various fun and exciting errors just trying to get a bare bones rails app up and running with the command given in the instructions:
rails dm_rails3_app -m http://github.com/snusnu/rails-templates/raw/master/dm_rails_master.rb
Has anyone managed to get this working in WindowsXP?
