The problem is that, when running gem install bundler via ansible, you’re not initializing rbenv properly, since rbenv init is run in .bashrc or .bash_profile. So the gem command used is the system one, not the one installed as a rbenv shim. So whenever you install a gem, it is installed system-wide, not in your … Read more

So, if you’re not going to release a gem, just go ahead and fork (assuming the license allows it) and don’t worry about it. That’s 100% OK and even expected behavior at this point.
