go golang的get get命令没有响应

I am facing a strange situation. I tried to run:

go get -x github.com/hooklift/gowsdl
cd.
git clone https://gopkg.in/inconshreveable/log15.v2 /home/usr_a/gocode/src/gopkg.in/inconshreveable/log15.v2

And I don't see this command giving any response. It never returns.

This is my $GOPATH:

/home/usr_a/gocode

and $GOROOT:

/usr/local/go/

However, the version shows like this:

go version go1.4.2 linux/amd64

Any idea, where am I going wrong or can point me to the way we install github module in golang?

It happens because of old version of git.
