Hello,
I tried installing virtualbox from packages, building it from sources,
trying the GENERIC kernel but everytime I can't start the kernel module
'vboxdrv', it says:
"KLD vboxdrv.ko: depends on kernel - not available or version mismatch.
linker_load_file: Unsupported file type"
The virtualbox module needs to be in full sync with the kernel. Most
probably the sources being used by the cluster for building packages on
head are a little different from yours, so the kernel module is not in
sync.
You will need to build the kernel module yourself to actually match your
kernel sources.
It's not really a problem or a bug, it's how it works. On head there is
no warranty about the KBI. This cannot happen on releases and stable
because the KBI is not going to change there.

I don't think this is true. While shareable libraries have fixed ABIs, I
believe the KBI can change even in STABLE branches. If a security fix
requires it, it might even change in a RELEASE. I my be wrong about this,
but I recall having to re-build the VB kmod port even withing a minor
version (i.e. STABLE).
We try hard NOT to change the KBI within a single stable branch.
we do things like add spare fields before we make a new stable branch
to help with this.
In any case, I do strongly recommend the use of PORTS_MODULES in
/etc/src.conf to assure that the kernel modules always get re-built when
the kernel is re-built. so that the sources, the kernel, and the module are
in sync. The PORTS_MODULES are re-installed as a part of the "make
installkernel", so things are almost safe, but beware of "make
reinstallkernel" as it does not do the right thing. (See
