Self-sustaining Mars colony?

OK, this issue halfway came up in another thread here but I'm curious. What do you think it would take to make a self-sustaining Mars colony? I would probably say the ability to grow food, produce drinkable water, power and breathable air, extract necessary raw materials and use the to manufacture needed parts and tools, and repair machinery as needed. People are pretty tough and could do without a lot of the comforts we take for granted.
Happy freelancer and Mars One candidate. I blog if anybody is interested.
