I did, a million times, hence the frustration.

That looks good. I do have ~/.R/check.Renviron which likely gets in the way.
I even tries to (easily) escape from that via Docker but then the most recent
r-devel build on Docker blew up over something with DATAPTR (uggh).

The unset trick is good. That may do it.
