mysqlclient.so.14

Does the following look familiar to you?

Error: Missing Dependency: libmysqlclient.so.14()(64bit) is needed by package perl-DBD-MySQL

I was getting this and several other variations while attempting to update/install some packages on CentOS 4.  It was strange because I could find the exact package it was talking about with a manual search.  However, doing a "yum search mysqlclient" didn't return any package for me newer than mysqlclient10.

Here's an easy solution:

yum remove mysqlclient*
yum --enablerepo=centosplus install mysqlclient14*

From here on you should be good to go...
