[R-SIG-Mac] rlang and the new R version 4.1.0

[Hans W]

Following this tip I had to remove and reinstall one after the other
the following packages:

    rvest, rlang, magrittr, xml2, stringi, ellipsis,
    fansi, utf8, vctrs, tibble, Rcpp, lbfgs, and GauPro

each time restarting R to make sure. Then the application worked again.
Does this mean I would be better off deleting all of my installed
packages and starting a fresh R?
Was this even a requirement for installing R version 4.1 on macOS -- a
requirement I didn't get?

Thanks for the help  --HW
