mysqlclient libraries missing in binary version 4 for Aix 5.2

[jose]

Hello.
I have installed binary version for aix 5.2 and when i try to compile
cyrus-sasl with mysql support it don't find mysqlclient libraries.
I use --with-mysql=/usr/local/mysql/ to build but i get:

checking for mysql_select_db in -lmysqlclient... no
configure: WARNING: MySQL library mysqlclient does not work
Doesn't it include client libraries ?
Thanks.
