Please describe how you installed Ruby and provide your schedule.rb and resulting crontab.

FWIW, I'm getting a similar issue, the cronjob seems to be running under "sudo" or some other user that doesn't have access to the deploy user's installed ruby and gems, it only has access to the system ruby/gems.

I installed whenever using capistrano from my development machine. Thanks for any help.
