As explained in <1546860281.3311.22.ca...@debian.org>, I think there is
no bug.

ldd lists libopenblas.so.0 as a dependency, but it is not actually
needed. I guess it's only listed because it's a *indirect* dependency
through libblas.so.3, when openblas is selected as the BLAS
alternative.

As a matter of fact, R runs fine without libopenblas-base installed.
