The math/abs port does not build on FreeBSD-2.2.8. I realise that there is no longer any guarantee that ports should build on 2.2.x systems, but the change required is minimal. I would be extremely surprised if this change breaks anything for 3.x or 4.x users. I am sending a small patch, which I hope will be used.
State Changed From-To: open->closed Update committed with a few minor mods. Thanks!
