Running metrical with rubygems-bundler

[ogredude]

When using rubygems-bundler, all the gem binstubs get a "bundle exec" wrapper, which causes Metrical to not work.

The solution is to add this line to your .bash_profile and gem regenerate_binstubs.

export BUNDLER_BLACKLIST="metrical churn flay reek roodi rcov saikuro rails_best_practices"
