[완료]왕초보 질문! qmake 버젼이 이상합니다.

우분투에서 qt4를 깔아볼려고 인터넷 뒤져서 깔았어요.
sudo apt-get install libqt4-core [libqt4-dev, libqt4-gui, libqt4-dbg, qt4-designer, qt4-dev-tools]
잘 깔린것 같은데 qmake 버젼을 확인하면
dreamer@dreamer-desktop:~$ qmake --version
Qmake version: 1.07a (Qt 3.3.8b) <- 이렇게 qt버젼이 QT 3.3.8b로 나오는것은 무엇때문일까요?
Qmake is free software from Trolltech ASA.

그래서 컴파일할때 다음과 같은 에러가 나요.
dreamer@dreamer-desktop:~/Test$ qmake -project
dreamer@dreamer-desktop:~/Test$ qmake
dreamer@dreamer-desktop:~/Test$ make
g++ -c -pipe -g -Wall -W -O2 -D_REENTRANT -DQT_NO_DEBUG -DQT_THREAD_SUPPORT -DQT_SHARED -DQT_TABLET_SUPPORT -I/usr/share/qt3/mkspecs/default -I. -I. -I/usr/include/qt3 -o hello.o hello.cpp <- 자꾸 qt3경로을 탐색합니다.

어떻게 하면 되는 거죠?
제발 좀 갈켜 주세요. 흐흐흑
