[chef] Removing root's password results in 'ruby-shadow not installed' error.

["Jason J. W. Williams" < >]

Hi,

I'm trying to write a recipe that will create a default user and
remove root's password on an Ubuntu 10.04 box. Creating the user (with
password) works fine. However, when it hits this:

 user "root" do
    action :modify
    password "*"
 end

I get this traceback about ruby-shadow not being installed:

I've tried setting the root password to an actual hash but I get the
same error. Any help is greatly appreciated.
