Hi Jonathan,

Could you please send me the output of:

$ python --version
$ python -c 'import boto; print boto.Version'

Also, as a sanity test you can try the following with boto directly:

[~]> from boto.ec2.connection import EC2Connection
[~]> conn = EC2Connection('<aws access key>', '<aws secret key>')
[~]> conn.get_all_instances()

Obviously you'll need to replace the <aws access key> and <aws secret
key> with your keys. If this works for you without error then there's
definitely a bug in StarCluster. If not, then I would suspect an issue
between boto and your currently installed python version.
