Now that *is* dishonestly ignorant: you know full well that LDEPEND [1]
covers exactly that case.

As well as obviating the need for := in the cases that break installs.

And oh look, "required before build, but must be installed in ROOT, not
on BUILD machine"; now where have I heard that requirement before?

So there is a very easy way for the two to be associated, and to specify
the most common (or any other, should it be justified) dependency that
is in both, with the current syntax.

But you knew that, right? You just chose to ignore it. Tsk: that's hardly
academically rigorous. Bad form, old chap, simply bad form.
