I am working on a project that requires ruby 3.0.2 using the x86_64 architecture but I am on an M1 macbook (macos 15.0 Sequoia). I have setup my dev environment with openssl 1.1, readline, libyaml, and gmp from homebrew. When I try to install ruby, I get the following output.

Is there a compiler flag that could be used to bypass this error or another step I have missed to resolve this error and get my ruby install working?
