Fake fulfilled dependency without dummy package

[Ralf Mardorf <ralf.mardorf@alice-dsl.net>]

Hi :)

IIRC there's a command that can fake, that an unmet dependency is
fulfilled. I already searched for apt, dpkg, aptitude regarding to this
subject, but had no success.

Am I mistake, is a dummy package needed?
