I was getting set up following the blink example and I got this error. I had to set the environment variable manually myself. Perhaps this could be set to a reasonable default or be more clear in the book that you may have to set this yourself?

Good point. I don't think it is safe to set a default, but more documentation on it would certainly be a good thing.
