求助

请问下,我在安装SKIM中文输入时出现
[root@localhost skim-1.4.2]# ./scons install
scons: Reading SConscript files ...
Checking for kde-config           :  kde-config was found
Checking for kde version          :  3.1-12lp
Your kde version can be too old
Please make sure kde is at least 3.2
Checking for the qt library       :  qt was found as /usr/lib/qt-3.1
Checking for uic                  :  uic was not found - set QTDIR put it in your PATH ?
是怎么回事阿,谢谢
还有什么好的中文输入法阿,大家推见下
谢谢
