MySQL is installed and working. Postfix and Courier are checking the 
tables to transport incoming eMails already.
I do have it installed in /usr/local/mysql and I tried configuring with 
--with-mysql=/usr/local/mysql but this doesn't help. I still get the 
first and the second warning messages.

When I do a locate on mysqlclient it's in:

/usr/lib/libmysqlclient.so
/usr/lib/libmysqlclient.so.12
/usr/lib/libmysqlclient.so.12.0.0
/usr/lib/libmysqlclient_r.so.12
/usr/lib/libmysqlclient_r.so.12.0.0
/usr/lib/mysql/libmysqlclient.a
/usr/lib/mysql/libmysqlclient.la
/usr/lib/mysql/libmysqlclient.so
/usr/lib/mysql/libmysqlclient.so.12
/usr/lib/mysql/libmysqlclient.so.12.0.0
/usr/lib/mysql/libmysqlclient_r.a
/usr/lib/mysql/libmysqlclient_r.la
/usr/local/src/mysql-standard-4.1.9-pc-linux-gnu-i686/lib/libmysqlclient.a
/usr/local/src/mysql-standard-4.1.9-pc-linux-gnu-i686/lib/libmysqlclient_r.a

Any idea what's wrong?
Maybe some ldconfig?

Thanks a lot.
