| After which 'sudo apt upgrade r-base-dev' ran. As far as I can tell, I haven't totally borked my system (yet), and R 4.4.1 runs just fine, plus I am not getting any further complaints from apt. But the process probably isn't quite as intended.

| https://emacs.ch/@pglpm/112664623789549089
| 
| and Dirk's suggestion to post this here.

This is mostly likely 'merely' a change coming from the other end
(i.e. Debian unstable/testing where I did what [1] shows) and which is out of
sync on a four years older (!!) release like focal until a) someone tells us
and/or b) someone sends us a tested / improved build recipe.

Most likely Michael (once he is back from a short trip) can just make an sed
call to adjust the debian/control file gets from my (current, Debian
unstable/testing) sources for these backports; switching pkgconf back to
pkg-config may be all it takes.

For what it is worth, I built also a 'local' build on 23.10 and it had no
issues. Focal is older, you value its stability but there will an occassional
'tax' to pay on these deltas.

Thanks for reporting it though. These things can only be improved if we're aware.
