I've been trying to get emulators/virtualbox-ose-kmod to compile from 
ports on a clang built 9-STABLE:

  # uname -v
  FreeBSD 9.1-STABLE #0 r251391M: Tue Jun  4 09:47:42 PDT 2013 
root@fb9build.jetcafe.org:/usr/obj/usr/src.amd64/sys/GENERIC  amd64
  # cc -v
  FreeBSD clang version 3.2 (tags/RELEASE_32/final 170710) 20121221
  Target: x86_64-unknown-freebsd9.1
  Thread model: posix

After some work I can get it to compile, but then I get this:

  # kldload /boot/modules/vboxdrv.ko
  kldload: can't load /boot/modules/vboxdrv.ko: Exec format error
  # dmesg | tail -2
  KLD vboxdrv.ko: depends on kernel - not available or version mismatch
  linker_load_file: Unsupported file type
  # kldxref -d /boot/modules/vboxdrv.ko
  ...
  /boot/modules/vboxdrv.ko
    depends on kernel.901505 (901505,999999)
    module vboxdrv
    interface vboxdrv.1
  # kldxref -d /boot/kernel | grep -C 3 /boot/kernel/kernel
    depends on kernel.901504 (901504,999999)
    module ppi_ppbus
    depends on ppbus.1 (1,1)
  /boot/kernel/kernel
    depends on kernel.901504 (901504,999999)
    module xpt
    depends on cam.1 (1,1)

What's going on here and how can I debug this one? It seems that the 
module vboxdrv.ko has the correct versions.

Thanks in advance for any assistance anyone can provide. :)
