[yt-dev] Packaging.

Hi Nathan,

That appears to work as it built the environment and `conda install ...`
added packages to my environment.

One mistake I made was that I originally downloaded the "latest" OS X build
of Miniconda, but that happened to be Miniconda3, which is python 3 based.
 Trying to build the environment with that yields an error regarding
incompatibility of yt and python3.3, as it should.

Chris
