Open Stack

Hey, all.  I'm writing some wrapper scripts to do some maintenance, and 
decided to install the client on my desktop Ubuntu machine just for 
ease-of-use.  And my script crashed and burned.  Initially, I'd assumed 
it was me screwing up Ruby... but then I realized that I'm getting 
completely different output from two different openstack clients, both 
showing v. 2.3.0 (with "-2" for the Ubuntu packages):

---------------

WAT?  Can someone essplain what I've got going on, here?  I admit that I 
vastly prefer the desktop's output -- I don't have to keep looping 
through stuff to pull key/value pairs -- but I've coded for the server's 
output.  More to the point, I'm completely at a loss to explain the 
disparity.  Some environmental variable or something?

Other items of note:
* I sniffed the API calls -- they are both receiving the same 
information back from the server.
* YAML output has the same variations as the JSON.
* Straight non-formatted output is identical between the two clients

Thanks,
