Grateful for any updates on this problem.

I have been following and testing subsequent dub releases with 
Nix flakes (nix build) (on NixOS).

Dub 1.33.0 was released too soon after this report to take it 
into account;
Dub 1.33.1 released July 2nd still does not address the issue.

I would just like to be re-assured that the issue is not 
forgotten.

It would be wonderful to know that it has been sorted.
thanks,
Ralph
