cd src
./all.bash

now it gives me the error saying

##### Building Go bootstrap tool.

ERROR: Cannot find /root/go1.4/bin/go.
Set $GOROOT_BOOTSTRAP to a working Go tree >= Go 1.4.

any idea how can i fix this do i just need to set env variable or any other installation is needed ?

You need to have an installed Go version 1.4 or newer to build the recent Go releases. The build script defaults to some path but if it's not there you need to set GOROOT_BOOTSTRAP environment variable to point to a previous working Go installation.
