It is because the package 'r-rcpp@mine' has been built using
'r-minimal-3.6.2'. Examining the building log:

--8<---------------cut here---------------start------------->8---
g++ -std=gnu++11 -I"/gnu/store/...-r-minimal-3.6.2/lib/R/include"
-DNDEBUG -I../inst/include/  -I/usr/local/include  -fpic  -g -O2  -c
api.cpp -o api.o
g++ -std=gnu++11 -I"/gnu/store/...-r-minimal-3.6.2/lib/R/include"
-DNDEBUG -I../inst/include/  -I/usr/local/include  -fpic  -g -O2  -c
attributes.cpp -o attributes.o
--8<---------------cut here---------------end--------------->8---

The fix seems to implement kind of 'package-with-explicit' for R. I
have just tried now and I failed. Keep you in touch. :-)
