I think the idea was to upgrade, instead of have this newer version next
to the current version.  The upgrade involves a lot of rebuilding, and I
am stuck at compiling 'dub' with 3.9.1.

If we can instead apply this patch as (having both 3.8.1 and 3.9.1), we
can push it, and after that add the darktable patch as well.

Kind regards,
