Problem compiling with MySql support

Hi,

I am having problems compiling 1.3.2 with MySQL support. The system doesn't
seem to find part of MySQL (mysql_init on libmysqlclient):

]#
./configure --enable-start-stop-daemon  --prefix=/usr --with-defaults=speed 
--disable-docs --disable-ssl --with-mysql --with-mysql-dir=/usr

loading cache ./config.cache


Configuring for Kannel gateway version 1.3.2 ...

<....>

Configuring DB support ...
checking whether to compile with MySQL support... searching
checking for mysql_config... /usr/bin/mysql_config
checking mysql version... 3.23.58
checking mysql
libs...  -L'/usr/lib/mysql' -lmysqlclient -lz -lcrypt -lnsl -lm
checking for mysql_init in -lmysqlclient... no
configure: error: Unable to find MySQL client libraries

I am using RedHat 9 and I have the proper RPM packages installed:

]# rpm -qa |grep -i mysql
perl-DBD-MySQL-2.1021-3
mysql-server-3.23.58-1.9
mysql-devel-3.23.58-1.9
mysql-3.23.58-1.9

]# locate mysql.h
/usr/include/mysql/mysql.h

]# locate libmysql
/usr/lib/mysql/libmysqlclient.so.10.0.0
/usr/lib/mysql/libmysqlclient.so.10
/usr/lib/mysql/libmysqlclient_r.so.10.0.0
/usr/lib/mysql/libmysqlclient_r.so.10
/usr/lib/mysql/libmysqlclient.a
/usr/lib/mysql/libmysqlclient.so
/usr/lib/mysql/libmysqlclient_r.a
/usr/lib/mysql/libmysqlclient_r.so

Any hints?

Thank you in advance,
