Building with mysql support

I'm trying to build kannel with mysql support. I have mysql installed in
my home directory.

Now, I configure it like this:
./configure --prefix=/home/mario/Test/gateway-1.4.3/ --with-mysql
--with-mysql-dir=/home/mario/Test/mysql-5.1.32

This is the part of configure output concerning mysql:
checking whether to compile with MySQL support... searching
checking for mysql_config... /home/mario/Test/mysql-5.1.32/bin/mysql_config
checking mysql version... 5.1.32
checking mysql reentrant libs... -rdynamic
-L/home/mario/Test/mysql-5.1.32/lib/mysql -lmysqlclient_r -lz -lpthread
-lcrypt -lnsl -lm -lpthread
checking for mysql_init in -lmysqlclient_r... yes
checking mysql includes... -I/home/mario/Test/mysql-5.1.32/include/mysql
checking mysql/mysql.h usability... no
checking mysql/mysql.h presence... no
checking for mysql/mysql.h... no
checking mysql/mysql_version.h usability... no
checking mysql/mysql_version.h presence... no
checking for mysql/mysql_version.h... no
checking whether to compile with MySQL support... yes

Now, of course, make won't finish compilation because of 'missing' mysql.h.

Here is what mysql_config returns:
$ /home/mario/Test/mysql-5.1.32/bin/mysql_config --include
-I/home/mario/Test/mysql-5.1.32/include/mysql
$ /home/mario/Test/mysql-5.1.32/bin/mysql_config --libs
-rdynamic -L/home/mario/Test/mysql-5.1.32/lib/mysql -lmysqlclient -lz
-lcrypt -lnsl -lm



What am I doing wrong?
