Deployment Gemfile.lock woes

Error

 You are trying to install in deployment mode after changing
 your Gemfile. Run `bundle install` elsewhere and add the
 updated Gemfile.lock to version control.
  
 You have deleted from the Gemfile:
 * guard-pow
 * rb-fsevent

Gemfile

#This shows the proper way
# - Now when you deploy, it will ignore the gems in the 
#   development group and when you want to install the 
#   app on a computer that isn't a mac you can run bunlder
#   as `bundle --without darwin` the first time, and then 
#   every following time you can just run `bundle`, as bundler
#   is supposed to remember the 'without' option for subsequent runs

I found your gist googling. I've the exact same problem. Did you manage to fix it ?

I changed my gemfile to look like the above, then ran bundler again to update the gemlock file.

nice !
thanks
