[Mono-osx] Still trouble with 1.1.17

If 'mono DoubleElimination.exe' doesn't work after you've verified  
that the required environmental variables are set in your shell and  
you've made sure that X11 is running (do other X11 apps run - xterm  
for example?), open-x11 or macpack won't get you any further.

The following lines in the macpack loader script cause macpacked MWF  
apps to fail for me since the quartz backend isn't currently functional:

# Setup the environment for MWF if needed
if [ "$MWF_MODE" -eq "1" ]; then
     export GDIPLUS_NOX=1

As Andreas said, the X11 macpack option isn't for winforms apps. You  
might want to follow his lead and avoid macpack until it's updated.

Make sure that the MONO_MWF_USE_QUARTZ_BACKEND and GDIPLUS_NOX are  
NOT set. Try the printenv command to see what you have going on. If  
they are set (even if set to 0) running the app will fail (at least  
it does for me). Once you've verified that those aren't set and the  
DISPLAY variable IS set, then try running Terminal.app, X11.app and  
launching your app via 'mono DoubleElimination.exe'.
