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, Matthew -- Dr Matthew J Seaman MA, D.Phil. 7 Priory Courtyard Flat 3 PGP: http://www.infracaninophile.co.uk/pgpkey Ramsgate JID: matt...@infracaninophile.co.uk Kent, CT11 9PW
