macOS Mojave Gazebo9 build failure

[smnogar]

I'm attempting to get ROS Melodic up and running on Mojave and I'm running into Gazebo9 build problems. Current version of Gazebo9 is 9.4.1. The gist is here. Gazebo8 seems to build fine.

The last few lines of output are:

Thanks for the report. I started building and uploading mojave bottles on Friday and hadn't quite gotten to gazebo yet. I still need to build ignition-common, ignition-fuel-tools, and sdformat. In the meantime, it looks like the error is related to the schematic view in the model editor and graphviz support.

I just uploaded a mojave bottle without QGV / graphviz support, but you should be able to use it for your ROS Melodic work

Great, it works now. Thanks!
