Not certain this is actually a bug, so posting here.
I'm on Ubuntu 18.04.4 LTS, building R version 4.0.0. The "configure" and
"make" steps are successful, but the "make check" step fails when it
gets to this part of ./tests/reg-tests-1b.R:
?? > ## methods() gave two wrong warnings in some cases:
?? > op <- options(warn = 2)# no warning, please!
?? > m1 <- methods(na.omit) ## should give (no warning):

?? > setMethod("na.omit", "bla", function(object, ...) "na.omit(<bla>)")
?? Error: package 'codetools' was installed before R 4.0.0: please
re-install it
?? Execution halted
It appears to be picking up the older version of codetools from $R_LIBS;
if I unset R_LIBS, then it works just fine.
So I'm wondering, is it a bug, or is the user's own fault for having
R_LIBS set whilst trying to build R?
