The syntax docker is using requires go 1.4: https://golang.org/doc/go1.4#forrange

Since it looks like you're trying to build a package, I would recommend reading https://github.com/docker/docker/blob/master/project/PACKAGERS.md
It covers the requirements for properly building a docker package.

Cool Thanks @phemmer ; btw was the requirement to bump to Go 1.4 documented anywhere? I'm not getting "packager notices" for when Docker is released. We used to get a release announcement, the sha hash and what not. Be good to also get any build changes in that announcement (but we need to get that announcement process back). This is the 2nd release I've had to try to hunt down important information :)

Problem: Docker 1.7.0 uses Go syntax introduced in Go 1.4

Solution: Upgrade to Go 1.4
