Looks like you're missing
patch-lib_irrlichtmt_source_Irrlicht_CIrrDeviceLinux_cpp
which is in the message you linked to. Most likely you had no patches/
directory and patch(1) chose to create the new file in the parent (see
https://marc.info/?l=openbsd-ports&m=171628004714049&w=2).

That is the only error, the rest of the 200 lines were just warnings.
