[R] make check fails -- how to debug

[Barris, Wes]

I am trying to build R-3.6.2 on a Linux system running CentOS 7.7.1908.  "make check" fails.  How can I troubleshoot this to find out what is wrong?

R_PAPERSIZE=letter
cd R-3.6.2
mkdir CentOS
../configure --with-x=no --enable-R-shlib
make
make check
.
