I used: apt-get -t testing install golang, which gets me that same 1.5.3
version of Go (and I still think its a board game!).

Fully expecting not to need nonsense like that.

But that yields:

~# go get github.com/google/syzkaller
package github.com/google/syzkaller: cannot download, $GOPATH not set.  For more details see: go help gopath

Clearly this stuff isn't meant to be used :/ Why doesn't it set a system
GOPATH in profile.d or whatnot. Why do I, as a user, need to be bothered
with crap like this.
