Comment (by ryandesign):

 Replying to [comment:3 mciobanu]:
 > It turns out the warning I got about my DNS servers ("Your DNS servers
 incorrectly claim to know the address of nonexistent hosts") was somehow
 misleading. My understanding was that it could lead to mismatched
 checksums, but it can also lead to files not being found, and that's what
 happened.

 If a file is not found on one server, MacPorts will try another server.

 > Well, I fixed my DNS issues and that took care of the downloads, but now
 I get a segmentation fault. I'm attaching the end of the log (the whole
 log is 24 MB, and it seems too big).

 That segmentation fault in `onto2vocabularyclass` is #68452.
