That is not what his message says -- the biggest issue is that it is
unmaintained (except for multiple patches by CRAN) and the message asked
for a volunteer maintainer.
Rarely are packages archived (not removed) from CRAN because of failures
on macOS. In the only instances I recall it was because such failures
were easily corrected but the package 'maintainer' did not do so.
Looking at it, it is only because the Rmpi package fails to build on MacOS and
hence any packages that use it directly or indirectly fail to build. Is that
something that is fixable?
It does build, and I use it for the M1mac checks. But as the README
there says
"External libraries are where possible installed via minor
modifications to Simon Urbanek's 'recipes' at
https://github.com/R-macos/recipes . The main exceptions are those
which need to use dynamic libraries (such as openmpi ..."
I have never seen a Mac setup where MPI would fit well -- it is most
advantageous in clusters of many CPUs with fast interconnects, the realm
of modern supercomputers.
