Comment (by urilabob@…):

 Well, it's now a year-and-a-half later and the problem hasn't resolved
 itself: there are more misbehaving dns servers, and dnssec isn't taking
 the world by storm... Meanwhile, the error message isn't very helpful (I
 assumed, when I first read it, that the problem was servers with stale
 caches...). While I would vote for jmr's fix myself, if we aren't going to
 have it could we at least change the error warning to something like:
 "Your DNS servers incorrectly give a DNS response for nonexistent hosts,
 probably in an attempt to be helpful. This may cause checksum mismatches
 for some ports. If you encounter problems, we suggest switching to a more
 standard DNS for the duration of your macports session."
