Vagrant doesn't work with ruby 1.9.1?

[nedski]

Trying to run

 vagrant box add base http://files.vagrantup.com/base.box

on an Ubuntu Karmic box running ruby 1.9.1p243 doesn't work. It requires ftools which has been renamed in 1.9.1 (it's now called 'fileutils'). Error returned is:

nedski,

We're working 1.9 compatibility. In the meantime, please try the prerelease gem:

sudo gem install vagrant --pre

This already fixes the above issue you're having! Let me know of any other issues which come up please. Thanks!

Excellent -- I'm pulling down a base box now. Thanks for the quick reply.
