"Thou shalt not violate causality within my historic light cone. Or else."
I'd be very wary of making and distributing many copies of the machine (I'd make a few, for safety's sake) - who could you trust with one? - and equally wary of distributing goods to the needy - simply doling out food solves nothing, I'd want something that'd turn deserts into lush country, something like that. But managing the whole thing without screwing up horribly and/or being killed by some bunch of muppets who want the machine would be seriously tricky. None of the sovereign nations that're strong enough to hold their own would be trustworthy, and if you gave it to an organisation like Oxfam some government would take it by force... maybe the solution would be to create a bunch of limited replicators, ones that could only turn out one thing at a time, and give them to people. So make one that terraforms desert but can't be used to do anything more, and preferably make it so it wasn't obvious where it had come from, and then arrange for someone responsible to have that... phew.
