如何安装pyqt3 ?

在安装Amarok的lrcShow-II时，提醒需要python2.4 和 pyqt3，通过rpm -qa 来查看，发现只有python，没有pyqt3.因为我从没用过python,所以想请教一下大家，如何安装pyqt3?我下载的是PyQt-x11-gpl-3.17.4.tar.gz ，解压之后怎么安装？或者大家有比源码安装更好的方法？麻烦大家啦~~~

我进入解压所得到的文件夹，用% configure.py 命令运行了安装程序，是这样吗？好像没什么反映，也不知道成功与否...

到网上搜了一下，改了另一种方法执行安装程序：
$ chmod a+x configure.py
$ ./configure.py

运行之后，出现了很多错误：

./configure.py: line 23: import: command not found
./configure.py: line 24: import: command not found
./configure.py: line 25: import: command not found
./configure.py: line 26: import: command not found

./configure.py: line 61: disabled_classes: command not found
./configure.py: line 69: syntax error near unexpected token `('
./configure.py: line 69: `sipcfg = sipconfig.Configuration()'

难道是源码有错了？

$ python configure.py

谢谢gucuiwen .其实我已经有安装了，Amarok的歌词同步也实现了.
只是我不知道如何确定pyqt3已经安装而已.因为我用rpm -qa ,whereis, find 等命令都找不到pyqt3，所以就以为没有安装.
PS.：我现在还是不知道，呵呵.知道的麻烦告知，谢谢哈~~
