PX4-Autopilot: 'px4_sitl gazebo' errors when performing third build step

Hi there, I ran make px4_sitl gazebo and got tons of errors in the third build step. I ran source ubuntu_sim.sh before making I also followed the dependencies for ROS/Gazebo. I can run make px4_sitl_default jmavsim correctly but got the errors for gazebo. Thanks for your help!
