Your MySQL client libraries aren’t properly installed

必须将mysql下的lib加入到动态链接库中，否则在configure pureft时会出错
checking whether mysql clients can run… no
configure: error: Your MySQL client libraries aren’t properly installed
[root@renyiwei pure-ftpd-1.0.36]#
解决方法：
将/usr/local/mysql/lib/加入到/etc/ld.so.conf中 #我的mysql用源码编译安装在/usr/local/mysql，lib下面没有mysql文件夹
也可以echo “/usr/local/mysql/lib” > /etc/ld.so.conf.d/mysql.conf
然后执行ldconfig
