Not a precise analogy, but take a look at:

http://www.freebsd.org/cgi/cvsweb.cgi/ports/www/p5-RT-Authen-ExternalAuth/Makefile?rev=1.8;content-type=text%2Fx-cvsweb-markup

This is an add-on module for RT which had (at the time) to adapt to the
radically different layouts between rt-3.6.x and rt-3.8.x

In your case, look at ${OSVERSION} to switch between different behaviours:

.if ${OSVERSION} >= 900000
# FreeBSD 9.x and above

...

.else
# FreeBSD 8.x and below

...

.endif

Or you can have two different ports, and just use a test on ${OSVERSION}
to say if the port is appropriate on that version:

.if ${OSVERSION} >= 900000
BROKEN=	only supported for FreeBSD 8.x or below
.endif

and in the other port:

.if ${OSVERSION} < 900000
BROKEN= only supported for FreeBSD 9.x or above
.endif

	Cheers,
