Well, I tried to recompile - compiling ends like this:

cam_periph.o: In function `cam_periph_find':
/usr/src/sys/amd64/compile/DEBUG/../../../cam/cam_periph.c:301:
undefined reference to `__mtx_assert'
cam_periph.o: In function `cam_periph_release_locked_buses':
/usr/src/sys/amd64/compile/DEBUG/../../../cam/cam_periph.c:382:

cam_periph.o: In function `camperiphfree':
/usr/src/sys/amd64/compile/DEBUG/../../../cam/cam_periph.c:603:
undefined reference to `__mtx_assert'
cam_periph.o: In function `cam_periph_release':
/usr/src/sys/amd64/compile/DEBUG/../../../cam/cam_periph.c:409:

cam_periph.o: In function `cam_periph_hold':
