Linux – yum package conflict installing thesqlclient package

I'm trying to build and install Zabbix 1.8 on my CentOS 5.2 server. This server has MySQL 5.0 installed from the standard CentoOS 5.2 repository.

./configure ... is failing because of:

configure: error: Not found mysqlclient library

When I do yum list mysqlclient* yum says there are no matching packages.

So I did a yum install mysqlclient* but get this error:

Transaction Check Error:
file /usr/lib/mysql/libmysqlclient.so.15.0.0 from install of mysqlclient15-5.0.91-1.ius.el5.i386 conflicts with file from package mysql-5.0.77-4.el5_5.4.i386
file /usr/lib/mysql/libmysqlclient_r.so.15.0.0 from install of mysqlclient15-5.0.91-1.ius.el5.i386 conflicts with file from package mysql-5.0.77-4.el5_5.4.i386

How do I resolve this?
