[R-SIG-Mac] Installing openssl package in R-devel

[Simon Urbanek]

Probably the best is to remove (aka move aside) *everything* - both /opt/R/arm64 and /opt/homebrew (or at least rename it to move it aside). The openssl package provides a fallback, but only if it doesn't detect something that gets in its way. It gets really confused if you have various various pieces from different versions. Once you install openssl you can move things back since it will be statically linked, but please note that Homebrew breaks pretty much anything native so it's a good idea to disable Homebrew whenever you are compiling something native.

Cheers,
Simon
