Charles,
Did you try a build of the provided alpha, beta and rc releases made
available to allow you to ensure that the released version would build and
perform as expected?
FWIW the new 3.6.3 made ~ 12 hours ago are already available for Debian,
built for the Ubuntu backports at CRAN (thanks to Michael) and also in the
base Rocker container behaves as expected (and as the one RC build did):
edd@rob:~$ docker run --rm -ti rocker/r-base
R version 3.6.3 (2020-02-29) -- "Holding the Windsock"

And (to echo Martin Maechler) tcltk comes up as TRUE as it should.
