 I've  checked  this patch right now, it works for me for "buildworld"
and "buildkernel" but not for "installworld":

 mkdir -p /tmp/install.FxqSvHpP
progs=$(for prog in [ awk cap_mkdb cat chflags chmod chown  date echo egrep find grep id install   ln lockf make mkdir mtree nmtree mv pwd_mkdb  rm sed sh sysctl test true uname wc zic tzsetup; do  if progpath=`which $prog`; then  echo $progpath;  else  echo "Required tool $prog not found in PATH." >&2;  exit 1;  fi;  done);  libs=$(ldd -f "%o %p\n" -f "%o %p\n" $progs 2>/dev/null | sort -u |  while read line; do  $line;  if [ "$2 $3" != "not found" ]; then  echo $2;  else  echo "Required library $1 not found." >&2;  exit 1;  fi;  done);  cp $libs $progs /tmp/install.FxqSvHpP
