Bundler 1.15 fails to complete installation from source

Summary

When performing installation from source on a new system, install will fail to complete bundle install step if gem install bundler --no-ri --no-rdoc is used to install bundler. This will pull bundler version 1.15.0, which does not work with the current source for 9.1.4 or 9.2.0-rc7.

Steps to reproduce

Perform installation from source steps until bundle install ... step.

What is the current bug behavior?

Installation files with the following error:

...
Fetching state_machines-activerecord 0.4.0
Installing state_machines-activerecord 0.4.0
Downloading omniauth-google-oauth2-0.4.1 revealed dependencies not in the API or
the lockfile (omniauth-oauth2 (>= 1.3.1), jwt (~> 1.5.2)).
Either installing with `--full-index` or running `bundle update
omniauth-google-oauth2` should fix the problem.

What is the expected correct behavior?

Bundler should succeed.
