If you happen to still be running DragonFly 4.0 – that’s two releases ago and not supported – you may be noticing less ports are building.  There’s been enough significant changes in DragonFly since that release that it’s reducing the number of buildable ports.

DragonFly 4.0 to 4.2 is not a difficult jump, so jump when you can.  The converse of this, of course, is that there’s even more building on 4.2 and DragonFly-current.
