You are working too hard!
There is no need to rebuild anything except emulators/virtualbox-ose-kmod.
The system and kernel are fine. You just need to build the kmod against the
13.2 kernel sources. Since you have the sources on the system, all that was
required was to reinstall the virtualbox-ose-kmod port. no new kernel is
required. The port will install the kernel modules into /boot/modules and
they are ready to load either with a reboot or using kldload.
