i love spackle! it's always smart to have some around the house. be sure to keep the lid on tight, because it will dry out quickly. also, unless you have an inordinate amount of holes to spackle, buy the smallest tub as opposed to the large tub of it. you really only need a tiny bit, and spackle doesn't do well on very large holes. that requires something like plaster. i've also heard that, in a pinch, you can use white toothpaste (the traditional type vs. gel) to fill small nail holes.
