I deploy my application to an Ubuntu VPS. I followed the “deploy to VPS” railscast.
Everything went smooth, up until I added the following gem:
https://github.com/marceldegraaf/sisow
On my local development machine it works like a charm, but after I deployed it to my production environment, the rails application will not start anymore (500 Internal Server Error).
I have tried a number of “tweaks” to my unicorn configuration, deploy.rb and a bunch of other files, but nothing seems to work.
The weird thing is that when I use:
RAILS_ENV=production bundle exec rails c
I can use the gem without any problems (?)

I had the exact same issue. Restarting the unicorn service fixed it for me:
