When I try to install the Media Wiki v1.5.1 it stops after some time ...
i get the warning: 
You are using mySQL 4.1, however, PHP is linked to older client libraries. If you encounter 
authentication problems, see http://dev.mysql.com/doc/mysql/en/old-client.html for pertinent 
solutions. 

coult this be the reason of my error?
