Happy Building! :rocket::purple_heart:

This update seems to have broken part of our build that uses Fastlane, which in turn uses Ruby.
The issue we ran into looks similar to what was reported here.
We were also able to work around this issue by following one of the suggested solutions within that issue.

In summary, it seems like one of the updates to Ruby picked up an update to etc (1.1.0 → 1.3.0) and that is what caused the error we were seeing.
