Add a utility that requires the existence of a given executable (like ffmpeg) on PATH. Possibly just sugar for a general "abort unless this block evals true" utility.

Current thinking:

need :ffmpeg
# Oops! I need `ffmpeg`, and it isn't in your PATH.

need :ffmpeg, "to transcode audio"
# Oops! I need `ffmpeg` to transcode audio, and it isn't in your PATH.

need "MongoDB", :executable => "mongod"
# Oops! I need MongoDB, and `mongod` isn't in your PATH.

need "GIS files", :path => "/opt/gis-files"
# Oops! I need GIS files, and '/opt/gis-files' doesn't exist.
