After integrating changes in PR1, this is the output for an attempted install of caravel. This is output from command line in guest os. Ansible task also fails.

@dhafley Jumping in to see what's going on, I didn't have issues with this step last week and now I'm getting this same error, but it happens when trying to install Ansible dependencies (so very early in the build). StackOverflow is suggesting there might be another package needed, so I'm going to try this and report on what happens.

@dhafley This change to the Ansible plugin might also be the culprit, since it's installing the required dependencies for cryptography (libffi and libssl) in a different Python directory than Python 2.7 (needed for Caravel). Going to poke around the VM and will continue updating as I find things.

UPDATE: I misread the issue for the the plugin originally. It's part of the issue since it hasn't updated in over a year. The suggested change is needed to work with Ansible now since something changed recently within Ansible. That change was not committed to the main project, so a local version of the plugin with the change made to its guest_script.sh would be needed. Still trying to figure out how to install a local version of the plugin to test this out, will update if I get it going.

Here's a workaround:
vagrant ssh
sudo apt-get install libffi-dev
sudo apt-get install libssl-dev
Exit the VM by hitting ctrl+D
Then run
vagrant provision
