結論

以下記事で解決。

M1 MacでRuby 2.4〜3.2をrbenvでビルドする最小限のセットアップを全部調べた

手順のコピペ

eval "$(/opt/homebrew/bin/brew shellenv)"

export PATH="$HOMEBREW_PREFIX/opt/bison/bin:$PATH"

export LDFLAGS="-L$HOMEBREW_PREFIX/lib"

export CPPFLAGS=""

export optflags=""

export OPENSSL_CFLAGS=""

export RUBY_CONFIGURE_OPTS=""

現在のBashのみで設定を変更するのがポイントっぽい?

このへんはネットの記事コピペしてやることが多いから、自分で解決できるようにならなきゃなぁと思いつつ･･･

このあと普通に

rbenv install 3.1.0

などで普通にインストールできた。
