apache+php5 问题,请帮忙.

[root@web-huyi ~]# /usr/local/apache/bin/apachectl -k start
Syntax error on line 234 of /usr/local/apache/conf/httpd.conf:
Cannot load /usr/local/apache/modules/libphp5.so into server: /usr/local/apache/modules/libphp5.so: undefined symbol: libiconv_open

apache 启不来.同样的配置在另外一台机就可以.
是什么原因呢.
http.conf
LoadModule php5_module        modules/libphp5.so
应该没问题.
libphp5.so也存在.

undefined symbol: libiconv_open

貌似要重新编译iconv?
应该是楼上说的,
原来是找不到libconv.so.2这个文件,报错信息,误导我.
