[Mono-osx] Still trouble with 1.1.17

[Aaron Flynt]

What do you get when you open Terminal.app, and type "echo $DISPLAY"?  
I think maybe /etc/bashrc doesn't set the display environment  
variable on a default install. I have the following in mine:

#Set the 'DISPLAY' environmental variable for running X11 apps from  
terminal:
DISPLAY=:0.0
export DISPLAY

Perhaps the LOADER script in mcs/tools/macpack should be modified to  
set the DISPLAY variable if the X11 backend is being used. Maybe test  
to see if it's empty and set it to some reasonable default (like : 
0.0) if necessary.
