just did out of curiosity, different error:

it appears to build but the result of my build is not available 
to me ... i guess unless I take some additional step that I have 
never had to... but thanks.

making sure HOME directory is set (in the nix "buildPhase" or 
"preBuild" as I ended up doing) to wherever nix chooses to do its 
build by default (pwd) is a better solution (my guess: it seems 
that somehow in dub HOME has been lost and some action of dub is 
now taken on root following an empty HOME)
