Actually, it's illustrated, somewhere, that you (read: a package) should
say "Depends: foopackage | virtual-foo", indicating a preferred - or a
random if all are equally preferred - package providing the virtual
package. I think this is precisely because apt refuses to pick for you.
And note my choice of words: refuses; I was told this is deliberately (not
by Jason though, so the question is whether whoever told me so was
authorative on the issue)
But in any case it means that there is a minor FTBFS bug in gnome-lokkit.
