I'm attempting to build a package using pbuilder, and would prefer to not install build dependencies on my host computer so I can keep it clean. Whenever It try to build a package, I get the following output because I don't have the dependencies installed.

$ pbuilder-dist saucy i386 build nautilus_3.8.2-0ubuntu1.dsc

How do I update pbuilder so it will resolve the dependencies automatically within it's own environment?
