Error while building Burrowbeat

Hi,

I have downloaded Go lang 1.7 in my Linux machine and I am trying to build Burrowbeat as per this guide https://github.com/Goomzee/burrowbeat

I have set ${GOPATH} using the command export GOPATH=/myfiles/gopath/

I have downloaded the zip file from https://github.com/Goomzee/burrowbeat and extracted it to /myfiles/gopath/. From the directory /myfiles/gopath/github.com/goomzee/burrowbeat-master, I triggered the command make, which is showing the following error;

make update
make[1]: Entering directory `/myfiles/gopath/github.com/goomzee/burrowbeat-master'
make[1]: *** No rule to make target `update'.  Stop.
make[1]: Leaving directory `/myfiles/gopath/github.com/goomzee/burrowbeat-master'
make: *** [setup] Error 2

Why is this happening and how can I fix this? Thanks.
