Upgrading MySQL to 4.1

I'm running a 9.2 box with mysql 4.0.21-4.4, people here need to use subqueries, i recommended using postgresql, because they'll probably need other features in the future, but they want to stay with mysql. I googled a lot looking for an 4.1 rpm for suse, just found the rpms of SuSE 9.3, tried to upgrade my installation with them, but there i enter and infinite list of dependencies (it starts with libmysqlclient.so.12 needed by perl-DBD-mysql). I could force the upgrade, but i don't want to break anything. Any suggestions to upgrade it?, (without exporting - installing mysql.com rpms - reimporting, i would like to use suse' rpms) CI.-
