听说QT 4可以支持播放多媒体文件了，下了个试试，结果如下：
Phonon support cannot be enabled due to functionality tests!
Turn on verbose messaging (-v) to ./configure to see the final report.
If you believe this message is in error you may use the continue
switch (-continue) to ./configure to continue.
是不是开源版的还不能使用这个功能，还是怎么回事？望高手指点。
