VierualBox-kmod fails to build on -CURRENT

[Vladimir Kushnir]

Hi
Well, the problem is:
I'm trying to build VirtualBox{*} on amd64 10.0-CURRENT. The very first 
port, virtualbox-ose-kmod fails with

/usr/ports/emulators/virtualbox-ose-kmod/work/VirtualBox-4.0.12_OSE/out/freebsd.
amd64/release/bin/src/vboxdrv/freebsd/SUPDrv-freebsd.c:104: error: 
'D_PSEUDO' undeclared here (not in a function)

And indeed, threre's no D_PSEUDO flags in /usr/src
Any help?

Thanks in advance,
Vladimir
