RosStream Plugin does not load: DataStreamROS::clockCallback not implemented

[lilioid]

Upon startup, PlotJuggler prints the following error message:

"libDataStreamROS.so" :  "Cannot load library /opt/ros/melodic/lib/plotjuggler/libDataStreamROS.so: (/opt/ros/melodic/lib/plotjuggler/libDataStreamROS.so: undefined symbol: _ZN13DataStreamROS13clockCallbackERKN5boost10shared_ptrIKN13rosgraph_msgs6Clock_ISaIvEEEEE)"

I was able to pinpoint this problem to datastream_ROS.cpp not implementing

PlotJuggler/plugins/ROS/DataStreamROS/datastream_ROS.h

Line 53 in ffc5e5a

void clockCallback(const rosgraph_msgs::Clock::ConstPtr& msg);

For some reason, I don't get this error in Kinetic. THANKS for reporting
