Hi,
Did you, as i wrote in an earlier response, install the mysql client library on computer2 ? (i.e emerge mysql on Gentoo or apt-get install libmysqlclient16 on Debian/Ubuntu)
You need the plugin to have the MySql interface in Qt but you still need the MySql client library to actually talk with the database.

Hope this helps
