I was simply following what upstream code was specifying as requriement
(which probably makes perfectly sense when not using a Debian chroot
that has no remote access).

I'll keep a record of these helpful hints in Git of that package.  It
turned out that I can use r-cran-av as an alternative which for the

Thanks again
