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.

I think you should re-read my e-mail more carefully -- those are not GNU extensions, those are headers used by pax, not tar. pax is a format inspired by tar and introduced in POSIX.1-2001, see http://en.wikipedia.org/wiki/Pax_(Unix)
