goi18n and go-bindata expected but not documented.

[HermannBjorgvin]

I am trying to figure out how to build this application.

goi18n and go-bindata are supposed to be installed globally? Is there a way around this?
I can't seem to find where the go-bindata repository is either.

Can you clarify on how I can build this?

Those tools are only development requirements and not required to build this project. You either use pre-build binaries, the Docker image or just go get github.com/Luzifer/ots it (the binary then will be in $GOPATH/bin/ots). In case you've already cloned the repo just execute a go build like in every other Go project and it will build.
