There have been quite a few changes since 0.9.0, so it is hard to tell, 
what is causing the difference for you. Which GUI classes are you 
actually using? In some cases it may be possible to work around the font 
allocation (which was causing your first problem), but if your are 
actually using GUI classes, they may have a reason to access a font.
In that case you need to initialise the backend, which gets done in the 
[NSApplication sharedApplication] call. Here you could try to redirect 
the X output, by pointing DISPLAY to another machine.
