The 'stable' links for binary packages on avalon now point at pkgsrc-2010Q2. This means pkg_radd will pull from a newer batch of packages.
Watch out - some of the newer packages will have newer dependencies, so you may be in for some number of upgrades to use these newer binary packages. If you keep a /usr/pkgsrc to match those binary packages (and you should if you are using them), you'll want to update it to match pkgsrc-2010Q2, also. Change /usr/pkgsrc/CVS/Tag to have 2010Q2 in it and 'cvs update -dP' is one way to do it.
