[StarCluster] Starcluster start cluster stuck at Configuring passwordless ssh for root

[Jonathan Goodson]

I followed the Quick-Start instructions at http://web.mit.edu/star/cluster/docs/latest/quickstart.html almost exactly, only changing a couple names. When I try to start the cluster everything works fine, it starts up two m1.small instances in my EC2 account, and successfully goes through the whole startup, until it gets to Configuring passwordless ssh for root, and then stops, and stays there indefinitely (I stopped it after 45 minutes and terminated the cluster) 

I don't even know where to start to try to figure out what is going on since it doesn't give me any error and I am not sure how to debug the script.
