Comment(by royliu@…):

 jk,

 Have you tried syncing with the MacPorts tree and rebuilding?  I believe
 everything will compile and everything will go fine ... until you actually
 try running a VM, in which case the VirtualBox will die horribly.

 Ryan,

 The reason for the compiler patches is that in Config.kmk, VirtualBox is
 setting its own compiler to be a non-LLVM GCC.  We'll have to override
 that.  I tried compiling with GCC 4.6, but there seems to be a problem
 with pragmas.  Thinking about patching GCC itself ... I'm wondering if I
 should revert my recent changes so that VirtualBox builds for all non
 Xcode 4.2 users.  It will stay broken for those on the edge.  What do you
 think?
