[chef] gem install knife-azure errors

[Ashutosh Narayan < >]

Hi Folks,

I am installing a knife-azure plugin using gem to make API calls to Azure for listing,

creating and deleting instances. But I get too many dependencies error.

One of them was rspec so I installed it, i now get another error message saying 

ffi.h is missing. Here is the error that was thrown on the console -

~]# gem install ffi

Building native extensions.  This could take a while...

..

.

ERROR:  Error installing ffi:
