Plugin not found: [git://github.com/user/project.git]
Certainly you could just download a from GIT project and copy/clone it to the vendor/plugins directory of your project. However you must admit it is a pain. Each time I installed manually a git-hosted plugin (so almost in 95% of Rails plugins :-P), I spent about half an hour looking for a solutions. And this morning I’ve eventually found it on www.ruby-forum.com.
Go to %ruby_installation_directory\lib\ruby\gems\1.8\gems\activesupport-2.3.5\lib\active_support\core_ext\kernel and open reporting.rb in a text editor.
(%ruby_installation_directory is c:\Rails by default)
