Issue with Clockwork to run scheduled sidekiq jobs.

I been using clockwork to schedule sidekiq background jobs, but now I’m having an issue when running Clockwork clock.rb. This is the error I’m getting:

$ clockwork clock.rb

I find it weird that is mentioning sinatra (some conflict between rails and sinatra?). Here'a gist with my clock.rb [https://gist.github.com/lurraca/5872705](https://gist.github.com/lurraca/5872705)

Sinatra is part of the development dependencies for Sidekiq. It's what it uses to show a web interface to watch threads and such.

The issue, however, seems to be in activesupport and Fixnum, which seems quite odd.
