Compass config.rb causing issues

[smallhadroncollider]

When using ChefDK with Vagrant, if I have a Compass config.rb file in my project directory, Berks tries to read it and fails:

The following berks command failed to execute:

    /usr/local/bin/berks --version --format json

The stdout and stderr are shown below:

It appears that you are not using the ChefDK. Please note that Vagrant Berkshelf
works best when used with the ChefDK, and other installation methods are not
officially supported.

Please download and install the latest version of the ChefDK from:

    https://downloads.chef.io/chef-dk

and follow the installation instructions. Do not forget to add the ChefDK to
your PATH.

The file works fine with Compass and should just be ignored by Berks.

Berkshelf is using the chef libs to load knife.rb or config.rb, the latter being what we've been moving to slowly. I'm not sure if there is an elegant way around this if it's in the same dir in path of lookup but setting a config.json for Berks might avoid this entirely.

It should only look for .chef/config.rb though, might be an error in one of the loader systems.

Good to know - I'll label this as a bug in that case. I figured we just searched up directories until we found it like knife.rb of old.
