I've never tried it on linux.  Check "echo $DISPLAY" and see if the 
display is set.

It can usually be solved by:

# export DISPLAY=":0.0"

The shell may not like this, so you can also use:

# DISPLAY=":0.0"; export DISPLAY

The full form is DISPLAY="<systemname>:0.0" but it will default to the 
local system if the system name is left out.

Nothing will work after the error about not being able to open the display.

(This is the way it is done on Linux, I assume OS X is running X-Windows 
but maybe not!).
