Plugin not found: ["git://github.com/collectiveidea/awesome_nested_set.git"]

I’m trying to install the awesome_nested_set plugin in a new project.
From the project directory, I enter script/plugin install
git://github.com/collectiveidea/awesome_nested_set.git . I keep
getting the error message “Plugin not found…” I’ve tried this off
and on all day thinking it might be a transient problem, but it’s not
going away. I can download the plugin directory from the site, so I
don’t think it’s a server availability problem. Can anyone suggest
what the problem might be or what I might do to start figuring it out,
please?

This is a known problem with Ruby 1.9. If that is what you are
running see the following for a fix:
