DK macro - Pop Death pact if pet is alive, if not, summon pet then use Death Pact

[Emo?]

As title says, i whant a macro that can be one button that trys to pop Death pact, if my pet isnt alive or summoned it should summon the pet and then try the death pact.

I know i could just do a mapped key in ISboxer that would try to pop both all the time, but i whant to know if there is a macro way of dooing it.
