Vagrant digital ocean plugin woes

$ vagrant install vagrant-digitalocean

Bundler, the underlying system Vagrant uses to install plugins,
reported an error. The error is shown below. These errors are usually
caused by misconfigured plugin installations or transient network
issues. The error from Bundler is:

An error occurred while installing nokogiri (1.6.4.1), and Bundler cannot continue.
Make sure that `gem install nokogiri -v '1.6.4.1'` succeeds before bundling.

$ sudo bash
# ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future gem install nokogiri -v '1.6.4.1'

Still the same issue persists. Then I tried:

$ ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future vagrant plugin install vagrant-digitalocean

Still same bug

The issues seem to be that ARCHFLAGS is not getting passed to the environment that vagrant is running "bundler install" from.
