libmysqlclient.so.16: cannot open shared object file解决办法

libmysqlclient.so.16: cannot open shared object file

suse linux10 

运行时报错libmysqlclient.so.16: cannot open shared object file，查看/usr/lib目录下有libmysqlclient.so.18存在，

ln -s过去也报错。我安装的mysql有

MySQL-client-5.5.25-1.linux2.6.i386.rpm 

MySQL-devel-5.5.25-1.linux2.6.i386.rpm  

MySQL-server-5.5.25-1.linux2.6.i386.rpm 

MySQL-shared-5.5.25-1.linux2.6.i386.rpm 

是哪里决定程序运行去链接libmysqlclient.so.16而不是libmysqlclient.so.18的呢？请牛人帮忙分析下，先谢过了。
