  The expectation is that xvfb-run is sufficient to do whatever it has 
to do to get itself working. If that means triggering the launch of 
Xquartz, then it needs to do that, and I'm also surprised that running 
Xvfb would not trigger it. The xvfb-run script is just a wrapper around 
Xvfb itself that handles xauth, avoids race conditions when picking 
various arbitrary/dummy screen parameters, and graceful shutdown. 
Probably the simplest (or at least first) test would be to see if just 
"Xvfb :10" from the commandline fails. I don't have a 10.10 box to test.
