New comment by anjandev on void-packages repository https://github.com/void-linux/void-packages/pull/18677#issuecomment-580981965 Comment: > Certainly it needs some depends. Set also `checkdepends="${depends}"`. Can be verified with `./xbps-src clean; ./xbps-src chroot` then import and do try anything with celery. This is 100% correct. I overlooked this. Celery depends on Kombu which in turn requires an amqp transport (https://docs.celeryproject.org/projects/kombu/en/stable/introduction.html#features). Most of celery's dependencies are not completely packaged. Should the default amqp transport (py-amqp) be a depend of Kombu?
