Indeed. Sorry I am late here but some of this was grarly. Also, as it should
be said, thanks to you and Ximin and others for the earlier help with the
(easier) building of all the r-cran-* packages.

Yep. Will update one patch we landed upstream ~ nine years ago (and switch to
the more universally used SOURCE_DATE_EPOCH) and then send the three or some
additional upstream patches.

One thing I missed, by the way, was a "simple" (?) to build reproducibly
locally to test. Did I miss one? My setup is ancient (pbuilder instead of
sbuild) so maybe that had something to do with it.

Tschoe mit oe,  Dirk
