I'm updating from Ruby 2.0 to 2.4.2 using RVM, and receive the following error messages during an install using $ rvm install ruby-2.4.2:

I'm… not quite sure what this means, or what I should do next. Any thoughts? I'm running macOS 10.12.6.
[Edit]: Here's a copy of the error log.
Found a fix as referenced in this RVM GitHub issue that involves installing zlib using brew and then re-installing ruby while pointing to that zlib directory. As someone in that thread pointed out, this shouldn't be necessary. Still not sure why the problem arose.
Steps
$ brew install zlib
$ rvm remove 2.4.2
$ rvm install 2.4.2 —-with-zlib-dir=/usr/local/Cellar/zlib/1.2.11
