[SCTP Serv-Clie 샘플 코드 컴파일 및 실행 시]

컴파일,,,
gcc -Wall -g SCTPServer.c -lsctp -o Server

$./Server 실행 시

./Server: error while loading shared libraries: libsctp.so.1: cannot open shared object file: No such file or directory

에러 뜨는데 이유가 뭐일까요,,, SCTP 샘플로 돌려볼려고하는데 정말 걸리는게 많네요

현재 리눅스 환경에서
lksctp-tools-1.0.10-3.el5.rfx.x86_64.rpm 패키지 설치한 상태입니다!,,
