So I guess git-archive --format=tar uses GNU tar extensions (not too surprising). So this is documented... and a documented incompatibilities between different tar/tar extensions. But this behavior of R is a bit unexpected - When R CMD check (which involves installing to a temporary location then loads it and runs various things) works and R CMD INSTALL itself does not.
