It's a canary, it means there is a misconfiguration in the system,
usually caused by existing packages having different dependencies than
what the user has now configured.

Common examples would be changing PKG_OPTIONS, *_VERSION_DEFAULT,
PREFER_*, etc. without then removing all existing packages built with
earlier settings.

In a pbulk environment it is almost certainly coming from:

  pkgtools/pbulk/files/pbulk/scripts/pkg-build:           DEPENDS_TARGET=/nonexistent

which is set after pbulk has already installed all the declared
dependencies of the package in question, thus exposing any situations
where the package still thinks there are others to be pulled in.
