Thanks a lot for the investigation.

I admit I have no idea. However, usually upstream of this type of
software is concentrating on amd64 exclusively since this is what is
practically used for gene sequencing.

Am I understand correctly that this might be a good reason to make
ncbi-vdb amd64 only?
Kind regards
Andreas.
