IMP的错误，请帮我看看！

难以抗拒

在Red Hat Linux 9上按照WXY的文章架构postfix,其它部份都可以正常运行，现在就剩IMP出现问题，我在IE里输入：http://192.168.0.193/horde/出现下面的错误：
Parse error: parse error, unexpected T_OBJECT_OPERATOR, expecting ')' in /opt/tomcat/webapps/Mintel/horde/config/registry.php on line 143

Notice: Undefined index: fileroot in /opt/tomcat/webapps/Mintel/horde/lib/Registry.php on line 517

Warning: Failed opening '/templates/index/frames_index.inc' for inclusion (include_path='.:/usr/share/pear') in /opt/tomcat/webapps/Mintel/horde/index.php on line 41
打开registry.php不知道怎么解决问题啊？
