우분투에서 루트(cern) 프로그램 설치후 error message 문의

안녕하세요.
이번에 우분투를 시작하게 되었습니다. 리눅스 시스템이 처음이다 보니 많이 서툽니다.

저의 문제점에 대해서 간략하게 적겠습니다.
우분투 8.04를 저의 컴퓨터에 깔았고, 그 이후 루트를 깔고 싶었습니다.
루트를 깔때 소스를 직접까는 방법과 바이너리를 이용하는 방법중 바이너리를 이용하는 방법을 택했습니다.
그리고 gcc도 설치하였습니다.
우분투 웹사이트에 나와있는 정보도 참고하여 적혀 있는것 그대로 하였습니다. (http://mirror.phy.bnl.gov/debian-root/ubuntu/)

그런데 루트를 실행해 보면 이상한 메세지가 뜹니다.
메세지는 아래와 같으며 무엇이 문제인지 답변해주시면 감사합니다.
웹에서 검색해보니 이것은 루트가 문제인게 아니라, 우분투가 문제라는 말이 있어서 글을 남깁니다. (참고: 이 사이트에서는 우분투 관계자에게 메일 보내라고 하였습니다. 해결책은 없었습니다.)

시스템 마다 약간씩 다르긴 하지만
아래와 같은 에러 메세지로 추측해보아, 라이브러리 충돌입니다.
실제로 BNL에서 제공해 주는 방법으로 설치를 하시기 전에 (http://mirror.phy.bnl.gov/debian-root/ubuntu/)
그이전에 root 홈에서 제공해 주는 라이브러리 및 소스를 컴파일 하신 것 같습니다. 그렇게 해서 생긴
경로 설정 오류인 듯 하기도 하고.

[code:7sdfwrf2]
Error in <TUnixSystem::Load>: version mismatch, /home/jars/Documents/download/cern/root/lib/libRIO.so = [b]52200[/b], ROOT = [b]51705[/b]
[/code:7sdfwrf2]

우분투 8.04 에서 BNL에서 제공해주는 방법으로 설치하셔도 됩니다. 제가 테스트 해본 걸로는 (컴퓨터 4대)
아무 문제 없이 잘 돌아갔었습니다.

다음과 같은 명령어로 경로를 확인해 보세요.

echo $ROOTSYS
echo $LD_LIBRARY_PATH

보통 BNL ROOT system packages는 /usr/local/bin 등등으로 나올겁니다. 그게 아니라 홈 디렉토리 /home/jars/Documents/.,… 으로 나오면 경로 설정 충돌입니다.
