这上面的错误信息是什么意思。怎么解决。
谢谢！

要先安装perl啊，你看提示不是很清楚么？

我刚开始学linux，问题可能很弱。麻烦各位了。
请问perl怎么装，要什么包？

就是perl的包啊，和gcc并列

请问，linux里面有没有象在windows里面，添加、删除组件的功能。把所有安装盘里面有的包都显示出来，并告诉你安装了哪些，没有安装哪些。
我在“添加删除软件”里面，只看到已经安装的包，没有未安装的包。

rpm -q 查询安装的包.perl肯定要先安装的.

[root@rhel5 ]#rpm -q perl
perl-5.8.8.-10
是不是说perl已经安装？

checking for XML::Parser... configure: error: XML::Parser perl module is required for intltool

是说缺perl里面XML的语法解析器的包

装上了，可是登录QQ後马上 又自动退出程序了。
是什么原因啊？

另外，安装RPM包的时候总是有依赖性检查不过关的，怎么解决啊，一个一个安装好麻烦啊
