Q: Why do I get a error: TkExtra (instance) message?
A: If all your attempts to run Swarm applications on MacOS X end thus:
error: TkExtra (instance) Abort trap
You need to start X11 before trying to launch a Swarm app with a GUI.
The error is caused by Tcl/Tk trying to open a window and complaining because there is no Xserver on which to open it.
