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

[Marc Schwartz]

Hi,

You might try a different CRAN mirror to see if perhaps the rlang binary 
that you are getting is corrupted.

Looking at CRAN for the package, the results for rlang on what is 
supposed to be R release on macOS:

   https://cran.r-project.org/web/checks/check_results_rlang.html

shows a header indicating that R devel is being used, not R release:

 
https://www.r-project.org/nosvn/R.check/r-release-macos-x86_64/rlang-00check.html

So, I am not clear if there is a macOS binary build issue that may be 
resulting in a conflict of sorts.

A spot check of other CRAN packages (including my own) shows the same 
use of R devel for macOS, and not R release, so perhaps there is a wider 
issue going on with CRAN builds, unless I am missing something here.

Simon (cc'd now) may be able to address that issue.

Regards,

Marc Schwartz
