[R] TTR curl issue on R 4.5.2 running OSX 11.7.1

[Michael McQuaid]

That sounds like a good suggestion except that openssl gets updated
periodically. Using homebrew, I just run

brew update && brew upgrade

regularly and all outdated packages are upgraded. I therefore try to use
brew in preference to other package installation methods where possible.
