请教cvsweb的问题

Question

安装cvsweb后不能显示正确结果，求助！
我的系统是用的RedHat AS4，在安装操作系统时就已经安装了自带的Apache服务器
cvs正常安装，并能正常使用

我安装cvsweb时的步骤如下：
下载cvsweb-3.0.6.tar.gz到root目录，解压文件
cp cvsweb.cgi到/var/www/cgi-bin/目录下，chmod a+x cvsweb.cgi，并编辑$c
cp cvswebconf到/etc/httpd/conf/目录下，编辑，@CVSrepositories = ('CVS'   => ['Repos',    '/repos/project'])

重启服务service httpd restart
访问页面提示：

Please contact the server administrator, root@localhost and inform them of the time the error occurred, and anything you might have done that may have caused the error.
