hypergo has been merged upstream and can be found in the HyperDex repo. This repo is no longer maintained.
First of all, install HyperDex. This is necessary because hypergo relies on HyperDex's official C client.
If installing via a package manager, you would want to also install the HyperDex dev packages. An example based on Debian would be, apt-get install hyperdex libhyperdex-client-dev libhyperdex-admin-dev libhyperdex-dev
Then, go get github.com/derekchiang/hypergo
Usable.
Thanks to tiborvass for contributing some of the original code via hyperclient.
