CFPropertyList dependency is getting on

[PilchardFriendly]

I'm trying to use betabuilder in a project with ios-calabash - in my bundler gemfile I have the following

gem 'calabash-cucumber'
gem 'betabuilder'

calabash wants CFPropertyList ~>2.2, betabuilder ~>2.0.0

Can betabuilder be less restrictive on CFPropertyList version?
