Issue installing pow on macOS Sierra 10.12.6

[Lewis John McGibbney]

Although issues installing pow should be reported elsewhere, I wanted to open an issue here seeing as it is listed as a prerequisite recommendation.

Apparently the successor to pow is puma-dev
https://github.com/puma/puma-dev
This is explained at basecamp/pow#543

I will update the README with directions for using puma-dev instead.

Moving the conversation to https://bugs.earthdata.nasa.gov/browse/EDSC-1961 or some subticket there.
