Unable to set up minion (TypeError: string indices must be integers, not str)

[Anush Jayaraman]

hello, I'm working on setting up an automation framework for my dev team. I read about salt stack and was wanting try this one out. I managed to configure it on my system running mac os x (mavericks) and another machine that I borrowed which os x as well (yosemite). I successfully started salt-master on my machine and salt-slave on the other machine. When I try to enable to the minion machine I'm seeing the following error. Can someone help me resolve this? Thanks in advance

Worked after installing pycrypto on the master!

Thank you
