Yeah, I spent a while googling this and I can't find any GOOD source that says that Haiti, even in lore, made a pact with the Devil.
I think he's referring to the fact that voodoo is somewhat common in Haiti? I don't know.
Either way, I first heard about this on the news earlier and I wasn't aware that the earthquake was of that great of a magnitude; at least, I wasn't aware of the alarmingly high death toll. I can imagine masses of people who have lost friends and loved ones, their home and other personal belongings, stores that they rely on, among many other things. The concept itself is truly depressing muchless the actual event, and I wish that I could do more aside from donating money - I am relatively powerless, though. RIP to everyone who perished, and best of luck to the survivors that are struggling to make it.
EDIT: Here's another cynical bitch that has no regard for thousands of innocent people that have died, and many others that have suffered the consequences.
