If _FreeBSD_version doesn't match, than VDEV_SUPPORT is not defined, and the
#ifdefs in os_freebsd.c will use the old code which doesn't provide the device
cloning.
As I mentioned in a previous message, this has the problem that a binary
package compiled under old FreeBSD 7 can't be recompiled dynamically under
FreeBSD 7.1 to do vmix or the reverse (i.e. If 4front distributes binary
packages, it will have to use a separate one for 7.1+). VDEV_SUPPORT is used
inside the core, and disentangling it so that the selection is done in the
wrapper alone would probably be complicated.
