In attempting to install Ruby with rbenv, I ran into the following build failures:

/usr/sbin/pkgutil --packages | grep CL didn't return anything initally, which mean that I had an old version of CommandLineTools and there's no way to update them per se, so I just had to remove and install fresh:
sudo rm -rf /Library/Developer/CommandLineTools
sudo xcode-select --install
/usr/sbin/pkgutil --packages | grep CL now returns:

brew install rbenv ruby-build openssl readline libyaml zlib
I ended up adding this to my ~/.zshrc:
# rbenv
export RUBY_CFLAGS="-Wno-error=implicit-function-declaration"
export RUBY_CONFIGURE_OPTS="--with-openssl-dir=$(brew --prefix [email protected]) --with-readline-dir=$(brew --prefix readline) --with-libyaml-dir=$(brew --prefix libyaml) --with-zlib-dir=$(brew --prefix zlib)"
# Load rbenv
eval "$(rbenv init -)"
rbenv install 2.7.3 (or whatever version you fancy) should work now :)
Nice! So the openssl version made difference there? Thanks for letting me know!
