VirtualBox-4.3.4 on 10-RC1: link_elf_obj: symbol RTThreadCtxHooksAreRegistered undefined

[Гуляев Гоша]

Hi All!
I tryin use VirtualBox 4.3.4 on latest -STABLE
FreeBSD home 10.0-PRERELEASE FreeBSD 10.0-PRERELEASE #0: Wed Dec 18 01:32:15 MSK 2013     user at home:/usr/obj/usr/src/sys/SERV  amd64

pkg info | grep -i virt
virtualbox-ose-4.3.4           A general-purpose full virtualizer for x86 hardware
virtualbox-ose-kmod-4.3.4      VirtualBox kernel module for FreeBSD

And when I tryin to load vboxdrv (manually or on boot) it gives an error:
Dec 18 08:35:56 home kernel: link_elf_obj: symbol RTThreadCtxHooksAreRegistered undefined
Dec 18 08:35:56 home kernel: linker_load_file: Unsupported file type

Kernel and its sources are synced.

What can cause that error?
