Are you running as root? I should probably display the stderr when this happens.

mwhudson commented

I pushed a change to do this, hopefully that helps.

You could update the README to indicate that root permissions are needed...
When I look at it now I can see the '#' prompt in your examples, but that's not an indication enough that root is required
