Review "Could not find celluloid-0.16.1" at running bundle install.

Getting this while running bundle install:

Fetching gem metadata from https://rubygems.org/.............
Fetching version metadata from https://rubygems.org/...
Fetching dependency metadata from https://rubygems.org/..
Could not find celluloid-0.16.1 in any of the sources

Removing celluloid from dependencies made bundle install finally worked.

It is really necessary?

Version 0.16.1 of the celluloid gem was yanked and is not available anymore. You will need to downgrade to 0.16.0 or upgrade to 0.17.x. I runned:

$ bundle update celluloid
