On a fresh install of freebsd 13.2 (I did make a new kernel, but I'm 
running GENERIC for this.

I used pkg install to get virtualbox-ose.  When I try to load the 
vboxdrv.ko, I get this error:

KLD vboxdrv.ko: depends on kernel - not available or version mismatch
linker_load_file: /boot/modules/vboxdrv.ko - unsupported file type
