Likewise, in order to build Go from source you need to already have Go 1.4 installed. In an OS where you by default download source and compile it (e.g. Gentoo, MacPorts on OS X), this means downloading an old, unsupported, and unmaintained version of Go just to build it to run a newer version. I had an issue recently where, on my laptop, Go 1.4 refused to build, and now I have no versions of Go on my laptop. I could install from binaries from the website, but that wouldn't satisfy dependencies so I'm stuck for now.
