Error message when installing restful_authentication from github

Anybody know if I'm doing something stupidly wrong here?

$ script/plugin install git://github.com/technoweenie/restful-authentication.git

removing: /Users/jcohen/dev/rest_with_rails/theater_login/vendor/
plugins/restful-authentication/.git
Initialized empty Git repository in /Users/jcohen/dev/rest_with_rails/

authentication.git"]

Everything *seemed* to get installed correctly in vendor/plugins/
restful-authentication, but the error message at the end is
disconcerting.

Any idea why this happening?

Thanks!

It's probably installing it via git (correctly) and then looking for it in your plugin sources and not finding it... at a guess.
