gazebo7 installation on MAC, Error: SHA256 mismatch

I've been following steps from http://dev.px4.io/simulation-gazebo.html , and got stuck pretty quicky on installing gazebo7:

System:Drones jakubczaplicki$ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
System:Drones jakubczaplicki$ brew tap osrf/simulation
System:Drones jakubczaplicki$ brew install gazebo7

==> Installing gazebo7 from osrf/simulation

==> Downloading https://bitbucket.org/osrf/gazebo/get/1969aea.tar.bz2
