The gcc and g++ compilers you point configure to here aren't right. I 
guess that's because the gcc version check logic in configure didn't 
account for mac os x using gcc 4.0.x. That's been fixed now. So, running 
./configure without any arguments should work fine again.

I've fixed makefiles so that now tweaks should be necessary.

I've fixed this problem. The src/VBox/VMM/Makefile.kmk had an obsoleted 
VBOX_OSE hack. If you've loaded VBoxDrv.kext and checked out kLdr 
correctly, it should work now. The kext can be loaded using the load.sh 
script found in out/darwin.x86/release/dist. kLdr you can get by 
entering src/VBox/Runtime and typing:
   svn co http://svn.netlabs.org/repos/libc/trunk/kLdr@3523 kLdr

The fake mode is very slow. It's not a priority (yet) to do anything 
about that as its only purpose it to serve as a milestone when porting 
VirtualBox to a new host OS.
