The current ntp cookbook fails to upload due to the recently added 1.9.x hash syntax in spec_helper with the following error:
While the chef omnibus server is running 1.9.x, it's detecting and using the wrong ruby for the syntax checking. In this case, it's the default 1.8.7 ruby on Ubuntu Precise. This is clearly a bug in the omnibus chef server, but I'm filing this here as this cookbook is the only one with this issue out of a large handful that I'm uploading.
Will repoint when I find the related ticket in chef server.
