I took to heart the advice to look at the suggested page in the wiki, https://wiki.netbsd.org/pkagsrc/x11. Running 'pkg_delete -r x11-links' returned no pkgs found (as best as memory can give me) and in the process of nosing around it seemed I had no x11-links installed.
Full Big-Dummy Disclosure: Yes, I had not correctly parsed the pkg_delete option '-r', and thought it meant "We will get rid of the pkgs dependent on x11-links but not delete x11-links itself." Then, in a fit of impulsiveness, I decided I needed x11-links (heck, it seems to show up everywhere...), which led to about an hour and half of pkgsrc building. But here's the rub: ===> Installing binary package of osabi-NetBSD-8.99.35 pkg_add: A different version of osabi-NetBSD-8.99.35 is already installed: osabi-NetBSD-8.0 pkg_add: 1 package addition failed *** Error code 1 BUT: # pkg_delete -f osabi-NetBSD pkg_delete: No matching package for basename `osabi-NetBSD' of `osabi-NetBSD' And, no surprise here: # pkg_delete -f osabi-NetBSD-8.0 pkg_delete: No matching package for basename `osabi-NetBSD-8.0' of `osabi-NetBSD-8.0' My spidey-sense is warning me that my pkg collection is seriously corrupt, and that I ought to give equally serious consideration to beginning over again, with a fresh install of -current.
