Not a precise analogy, but take a look at:

http://www.freebsd.org/cgi/cvsweb.cgi/ports/www/p5-RT-Authen-ExternalAuth=
/Makefile?rev=3D1.8;content-type=3Dtext%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=
:

=2Eif ${OSVERSION} >=3D 900000
# FreeBSD 9.x and above

=2E..

=2Eelse
# FreeBSD 8.x and below

=2E..

=2Eendif

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

=2Eif ${OSVERSION} >=3D 900000
BROKEN=3D	only supported for FreeBSD 8.x or below
=2Eendif

and in the other port:

=2Eif ${OSVERSION} < 900000
BROKEN=3D only supported for FreeBSD 9.x or above
=2Eendif

	Cheers,

	Matthew
