[The rebuilding is not your problem. . .

It reported a more up-to-date file. But looking the timestamp was in the future (tomorrow, almost 24 hours away): # ls -lT = /usr/obj/amd64_clang/amd64.amd64/usr/src/amd64.amd64/obj-lib32/tmp/usr/inc= lude/runetype.h -rwxr-xr-x 1 root wheel 3906 Nov 3 20:13:14 2017 = /usr/obj/amd64_clang/amd64.amd64/usr/src/amd64.amd64/obj-lib32/tmp/usr/inc= lude/runetype.h Apparently one or more of the times when I booted the virtual machine recently it ended up with a bad time and part of at least /usr/include has the problem with timestamps: # ls -lT /usr/include/runetype.h -r--r--r-- 1 root wheel 3906 Nov 3 22:48:30 2017 = /usr/include/runetype.h (The time for the active boot is fine.)
