OK. 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

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 at .
