    # We're going to download our cookbooks from the web

It looks to me like the syntax on Cheffiles changed since you first wrote this. I updated the Cheffile in my gist here: https://gist.github.com/3055132

I also moved the git pointers to what seem to be the current canonical homes for each of those packages, except for rvm which seems to still be externally managed. I also added a Cheffile.lock entry to gitignore.

Thanks much for the blog post! Was a huge help with getting this setup for me, and wanted to make sure the lessons I learned got reflected in the code.
