Problems installing exception_notification plugin

Hi,

I am, trying to install the exception_notification plugin for rails. I am using rails 2.3, and Windows 7 (64 bit)

The Rails 3 version is here: https://github.com/rails/exception_notification/ I can install it using git-bash thus: ruby script/install plugin git://github.com/rails/exception_notification/ This works fine.

However, I am trying to install the version of the plugin which is compatible with Rails 2.3 It is here: https://github.com/rails/exception_notification/tree/2-3-stable/ However, when I try the following in git-bash: ruby script/install plugin git://github.com/rails/exception_notification/tree/2-3-stable/ I get the error: fatal: remote error: rails/exception_notification/tree/2-3-stable/ is not a valid repository name.

Any ideas how I can install the 2.3 branch of this plugin? Thanks in advance.
