Problem with http://docs.emlid.com/navio/Navio-dev/rtklib/ -- rpi install not working?

I have a raspberry pi 2b with jessy
I follow these instructions
wget https://github.com/emlid/RTKLIB/archive/master.zip
unzip master
The archive contains ready to use RTKLIB binaries for Raspberry Pi:

cd RTKLIB-master/bin-rpi
Running RTKLIB

RTKLIB’s real-time processing program is RTKRCV, to run it type:

./rtkrcv

there is no folder created called “bin-rpi”

What should i do
