Problem:
Github may go down/timeout during deploy
Fix:
1. ssh into the server
2. cd to your current deploy folder
3. run bundle show 'name of gem' (shows the location of the gem install)
4. cd to the /gems/ path that is shown in the previous step
5. run ls -l to see the latest install of the gem
6. run rm -rf on that directory (the latest gem install)
