Untar this package
https://packagemanager.rstudio.com/cran/linux/bionic/latest/src/contrib/dplyr_1.0.0.tar.gz
There are no binaries inside this package from what I can tell.
I see from your log dependencies of dplyr were installed but not necessarily dplyr itself. Was Dplyr installed as a binary package?
On docker r-base 3.6.3:
options(repos=c(CRAN="xxxx://packagemanager.rstudio.com/cran/__linux__/bionic/latest/"))
> install.packages("dplyr")
Installing package into ‘/usr/local/lib/R/site-library’
(as ‘lib’ is unspecified)
also installing the dependencies ‘cli’, ‘pillar’, ‘purrr’, ‘ellipsis’, ‘lifecycle’, ‘rlang’, ‘tibble’, ‘tidyselect’, ‘vctrs’
trying URL 'xxxx://packagemanager.rstudio.com/cran/__linux__/bionic/latest/src/contrib/cli_2.0.2.tar.gz'

But then all packages are compiled for the most part except for ones with no C dependencies.
