LoadError: No such file to load -- /app/app/controllers/mixpanel-ruby

i'm getting this load error when trying to use on production
it seems to be working in development just fine
LoadError: No such file to load -- /app/app/controllers/mixpanel-ruby
thinking it might be the line where we do "tracker = Mixpanel::Tracker.new()"
its looking for a file called mixpanel-ruby in the controllers folder
