We can drop the sys.path hacking in various places by doing this. Additionally, by doing it in one place right up top, we can print interesting warnings in case the environment does not look correct. (See next commit.) If we ever decide to change how the environment is crafted, all of the "help me find my python packages" goop is all in one place, right in one function.
