I got that message when running out-of-date (ports tree updated few hours ago, system running i386 snapshot from Sep 17):
mail/maildrop,-utils # gdbm-1.8.3p0,gdbm.3.0,m.2.3,stdc++.42.0 -> So i did SUBPACKAGE=-utils make update... But out-of-date spits out the same message. Broken ports tree, or example of work in progres on the ports utils? -- viq
