我的red flag webmail server 4.0 安装一切正常，但安装完成后，启动提示失败
我的webmail安装目录为file:/webmail4，shell中进入该目录执行命令./startall出错如下：
Starting slapd: [ 确定 ]
Starting httpd: Syntax error on line 208 of /webmail4/www/conf/httpd.conf:
/webmail4/www/bin/apachectl startssl: httpd could not be started
Cannot load /webmail4/www/libexec/libphp4.so into server: /webmail4/www/libexec/libphp4.so: symbol errno, version GLIBC_2.0 not defined in file libc.so.6 with link time reference
[失败]
Starting up redflag mailserver: [ 确定 ] 请指点迷津，谢谢！
