Go's static typing goes a long way in helping catch breakage due to things like adding or remove symbols. (However, it does have some warts where incompatible versions may silently compile, like initializers.)

While Go doesn't have package management, it does have a framework (go get) for automatically fetching and compiling dependencies. However, people quickly realized that there's no way to pin dependencies; it will always fetch the master branch's HEAD, so if you "go get" a project, it will fetch some arbitary version depending what time of day it is. The community has devised various ways around it, and recent versions of Go have a way of resolving packages to a local "vendor" directory, but it's not a solved problem. There's no solution that stands out from the rest as particularly good or feature-complete when you look at the historical alternatives (Ruby's Bundler in particular).
