I typically have "PKG_DEFAULT_OPTIONS+=-cups" (among other things)
although some packages don't honor this option.

I had thought "lang/openjdk8" was such a cups-requiring package.  It
builds/installs cups when it is being built, but doesn't register a
run-time dependency (why it even wants/needs "cups" baffles me).

Checking its as-installed list of dependencies, "cups" is not in its
"Requires:" list.

That explains why "cups" didn't have any entries in it's "Required-by:"
list.  I think it got installed on my workstation likely as a side-effect
of my automated update with the binary packages produced by the build
host and previous self-hosting of package builds/installs on the
workstation itself.

So for the workstation, simply remove cups.  Possibly also hunt down
other "dead wood" packages--those with empty "Required-by:" lists that
were not user-requested packages.
