make: *** [dep] Error 2

Maybe we should check here?

if ds := s.sel.getDependenciesOn(q.id); len(ds) != 0 {
	s.fail(ds[0].depender.id)
}

Seems like a duplicate of #1437. Should probably be closed.

Dep was officially deprecated earlier this year, and the proposal to archive this repository was accepted. As such, I'm closing outstanding issues before archiving the repository. For any further comments, please use the proposal thread on the Go issue tracker. Thanks!
