Subject: [PATCH] Fix failing Travis builds:

Work around an unresolved Travis/Bundler/RubyGems bug:

* https://github.com/travis-ci/travis-ci/issues/8978
* https://github.com/travis-ci/travis-ci/issues/8969

Remove `dist: trusty` as that's the default:

* https://blog.travis-ci.com/2017-07-11-trusty-as-default-linux-is-coming
* https://blog.travis-ci.com/2017-08-31-trusty-as-default-status

Use the recommended Rubinius version (rbx-3):

* https://github.com/travis-ci/docs-travis-ci-com/pull/1534

Cache dependencies to speed up builds:

* https://docs.travis-ci.com/user/caching/

Automatically choose the latest versions of 2.x (e.g. currently 2.4.4 for 2.4):

* https://github.com/rvm/rvm/issues/4352#issuecomment-378675362
