centos6.3中安装ic6遇到问题

各位大侠，我在centos6.3中安装ic6遇到如下问题：
Exception in thread "mAIn" java. lang.Unsatisfied Link Error: /home/eda/installscape/iscape/runtime/LNX86/lib/i386/libawt.so: libXp.so.6: cannot open shared object file: No such file or directory

装不下去了，求助啊。

eda安装的图形界面都要用libXp.so.6，我装questasim的也是这样的，所以像ls说的，把libXp的库装上就好了
BTW，可以用RHEL4或者Centos4装，cadence推荐是使用这个系统
