root@zyp:/usr/local/src/lsof_4.55# make install
Please write your own install rule.  Lsof should be installed
setuid to root if you wish any lsof user to be able to examine
all open files.  Your install rule actions might look something
like this:
     install -m 4xxx -o root -g  ${PROG} ${BIN}
     install -m 444 ${MAN} ${DOC}
