ruby-install 0.8.3 has been released. This version explicitly pins the homebrew openssl dependency to openssl@1.1. OpenSSL 3.0 was released this month and is now available in homebrew. Unfortunately, ruby’s openssl bindings are still working on OpenSSL 3.0 support, so attempting to compile any current ruby version against OpenSSL 3.0 from homebrew will result in a compilation error. Until all actively supported versions of Ruby support OpenSSL 3.0, ruby-install will continue to compile against openssl@1.1 on macOS with homebrew.
