NameError: undefined local variable or method `lib' for main:Object

Hi!

This library is incredibly cool, thanks so much for making it :).

Unfortunately it breaks in one of my rails apps due to https://bugs.ruby-lang.org/issues/7536

I get:

NameError: undefined local variable or method `lib' for main:Object
script/rails:6:in `<main>'
/home/conrad/.rvm/gems/ruby-1.9.3-p327@rapport-web/gems/better_errors-0.0.2/lib/better_errors/error_frame.rb:62:in `eval'
/home/conrad/.rvm/gems/ruby-1.9.3-p327@rapport-web/gems/better_errors-0.0.2/lib/better_errors/error_frame.rb:62:in `block in local_variables'
/home/conrad/.rvm/gems/ruby-1.9.3-p327@rapport-web/gems/better_errors-0.0.2/lib/better_errors/error_frame.rb:62:in `map'
/home/conrad/.rvm/gems/ruby-1.9.3-p327@rapport-web/gems/better_errors-0.0.2/lib/better_errors/error_frame.rb:62:in `local_variables'

This is due to https://github.com/fblee/nokogiri-plist/blob/master/nokogiri-plist.gemspec#L2 being required by Bundler (we load that gem from a git URL in our Gemfile).

There's a pretty easy, though very unsatisfying, workaround, which is just to catch the NameError. Pull request coming up.
