I have compiled a 64bit VM on mac intel ; a carbon version. I have  
take the latest source from svn .
A had to fix a lot of methods which use int and replace it by sqInt.
But even if I manage to compile it the VM doesn't work.
When I open the image nothing happen and I am obliged to kill the  
process.
