I just removed old pkgsrc binary packages for DragonFly 2.6/2.7 from avalon, so if somehow you are running a version of DragonFly that old, and still using binary packages, you’ll want to upgrade. I’m pretty confident that describes nobody.
Also, I have plans for coordinating the next pkgsrc release of 2012Q1, due April 6th, with the probably next minor upgrade of DragonFly, 3.0.3. I wrote out my plans already, so go read. (plus followup)
