How to Ruby on Apple silicon
# Need to use ~/.zshenv, ~/.zprofile is not sourced when doing "arch -x86_64 /bin/zsh"
#
# From 'man zsh' (zsh 5.8.1 (x86_64-apple-darwin21.0))
#
# Commands are then read from $ZDOTDIR/.zshenv. If the shell is a login
# shell, commands are read from /etc/zprofile and then $ZDOTDIR/.zprofile.
# Then, if the shell is interactive, commands are read from /etc/zshrc and
# then $ZDOTDIR/.zshrc. Finally, if the shell is a login shell,
# /etc/zlogin and $ZDOTDIR/.zlogin are read.
