tcpdump를 설치해서 패킷 모니터링을 하려고 하는데요
 그전에 libpcap을 설치해야 한다고 하길래 설치하려고 하는데
 자꾸 에러가 나네요

 이것이 에러 메세지 인데요 마지막에 보면 flex가 없어서 그런줄 알고
 flex-2.5.4 설치를 했는데도 마찬가지네요
 그래서 bison이 설치가 안된거 같아서 설치하려고 하니
 checking whether m4 supports frozen files... no
configure: error: GNU M4 1.4 is required
 이런 에러 메시지가 뜨고요
 그래서 m4-1.4도 설치했는데 역시 마찬가지네요
 산넘어 산이라고 자꾸 엉뚱한 방향으로 흘러가는거 같은데
 모가 문제 인가요?
