Getting `warning: class variable access from toplevel` with bundler

[clowder]

Pretty simply if I run bundle exec rake lint I get the output below, if I just do a rake lint then puppet-lint runs fine. Is there a config step I’m missing? Or a bug?

$ bundle exec rake lint --trace
~/.rbenv/versions/1.9.2-p290/lib/ruby/gems/1.9.1/gems/puppet-2.6.12/lib/puppet/util/log/destinations.rb:99: warning: class variable access from toplevel

Gemfile

source :rubygems

gem 'rake'
gem 'puppet', '2.6.12'
gem 'puppet-lint'

Rakefile

require 'puppet-lint/tasks/puppet-lint'

That error is actually coming from Puppet itself. As far as I know, only puppet 2.7.x supports Ruby 1.9.
