I took a closer look:  I actually did get the window (hidden under my 
terminal window), and
interactivity worked partially:  I could use identify, for example.  But 
when I clicked on the red close
button on the graphics window, it kicked me right out of R:

Warning message:
quartz() device interactivity reduced without an event loop manager in:

CGGStackRestore: gstack underflow.

[Worked fine, then I clicked on the red button...]

 *** caught segfault ***
address 0xff020000, cause 'memory not mapped'

Traceback:
 1: identify.default(1:10, 1:10)
 2: identify(1:10, 1:10)

Possible actions:
1: abort (with core dump, if enabled)
2: normal R exit
3: exit R without saving workspace
4: exit R saving workspace
