Got the latest binaries last week (May, 23). 
Fiddled the request: `&Version=2012-11-05`
and the response is: `<CreateQueueResponse xmlns="http://queue.amazonaws.com/doc/2009-02-01/">`

Also _browsing_ `http://localhost:9324/?Action=ListQueues` returns
```xml
<ListQueuesResponse xmlns="http://queue.amazonaws.com/doc/2009-02-01/">
```
