an error everytime i want to do make -j4 buildworld:

-DMAGIC='"/usr/share/misc/magic"' -DBUILTIN_ELF -DELFCORE 
-DHAVE_CONFIG_H -I/usr/src/lib/libmagic 
-I/usr/src/lib/libmagic/../../contrib/file -c 
/usr/src/lib/libmagic/../../contrib/file/softmagic.c -o softmagic.So 
./mkmagic magic building static magic library WARNING: offset head 1.1;
