FYI in such situations it is quite often the case that the port itself cannot be compiled from scratch, at least in certain environments approximating the pointyhat one. Otherwise the package might compile but fail QA tests like whether the packing list is correct. Of course, such issues do not happen if you update between releases, since extensive QA goes into the release package set, so the upgrade process for users with less aggressive update schedules should be even better. >> No, they are.

Both of these issues sound like compatibility problems within RELENG_7. In principle we don't strictly support running binaries compiled for newer systems on older systems, but ABI breakage events should be rare and deliberate, and it is possible that these were made by accident. I have raised the memrchr issue with the developer and the release engineers. I don't know the cause of the fcntl issue though, so perhaps you could re-raise it on stable@. >> Glad to hear your experience was generally positive though. >> > > Yes, very positive.

Thanks! Kris
