Answer 1

You haven't stated which version of the ohai and nginx cookbooks you're using.

While I can't answer your question I can provide some advice on managing your cookbooks by using a dependency manager (think bundler for cookbooks).

Install Berkshelf

gem install berkshelf

Create a Berkshelf file

$ cat Berksfile

site :opscode

cookbook "nginx"

And use this to download all the cookbooks associated with nginx:

$ berks install -p cookbooks
Using nginx (2.0.0)
Using apt (2.3.0)
Using bluepill (2.3.0)
Using rsyslog (1.9.0)
Using build-essential (1.4.2)
Using ohai (1.1.12)
Using runit (1.2.0)
Using yum (2.3.2)

The "-p" option places them in the "cookbooks" subdirectory:

$ ls -d cookbooks/*
cookbooks/apt       
cookbooks/build-essential  
cookbooks/ohai     
cookbooks/runit
cookbooks/bluepill  
cookbooks/nginx            
cookbooks/rsyslog  
cookbooks/yum
