I am building a Vagrant configuration (for Nginx, PHP, and Postgres) with Chef Solo, using the databox cookbook to create databases in Postgresql during provisioning. I kept getting the error below, which I traced to databox::postgresql's eventual call (via database::paostgresql) call to the postgresql::ruby recipe. I tried running postgresql::ruby directly in my run list, and it produces the same error.
Logging into the VM and running sudo /opt/ruby/bin/gem install pg works, and the rerunning vagrant provision works too. However, as I understand it, the whole point of the postgresql::ruby task is that it installs this gem!
Here is the output from a Chef run that runs only this recipe (edited slightly for readability):

Chef never successfully completed! Any errors should be visible in the
output above. Please fix your recipes so that they properly complete.
I'm not doing anything unusual in this failing run - the VM is a stock Vagrant Ubuntu 14.04 x64 image built with Packer - and the only thing Packer did to the image is installing Chef and the VirtualBox extensions.
Any idea what's going on here? I don't see anyone else complaining about this - am I doing something wrong or is no one else using this recipe?
Chef is version 11.12.8.

I also posted this as an issue on the postgresql cookbook itself, but I figured it might get more exposure here.
It appears that this issue only happens when Chef is installed as a gem, as far as I can tell.
I switched from using the Chef Gem to using Omnibus, and I was able to get it working correctly.
