The kubernetes can't find correct go in ubuntu

My OS is ubuntu 14.04.3 Server, and I want to build kubernetes.

Firstly, I use "apt-get" command install Golang, but the version is 1.2.1, so I use apt-get --purge autoremove command to remove it.And install the newest 1.5.1 from golang website.

But executing make command, it seems kubernetes always "think" current golang is 1.2.1:

But the go in "PATH" is 1.5.1:

$ echo $PATH
/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games:/usr/local/go/bin
$ which go
/usr/local/go/bin/go
$ go version
go version go1.5.1 linux/amd64

So how can I fix this issue?

As explained in "How can you completely remove a package?", a sudo apt-get --purge autoremove might have removed go completely.
But that doesn't mean it has cleaned what was compiled before

Make sure that /home/nan/kubernetes/Godeps/_workspace and /home/nan/kubernetes/_output are deleted after a make clean (See issue 16771).
Make sure /usr/local/go/pkg is writable for the user nan. (See hack/lib/golang.sh)

Finally, issue 16229 mentions:

> Would be nice to at least update the docs to indicate that you can't use go>1.4.

So try and install go 1.4.x only.

Update: the OP Nan Xiao reports in the comments having managed to build it with go 1.5.1 or 1.5.2 without any more issue.
