Unknown MySQL server host '' (3)

Hi, i get the following error when trying to install omeka.
Unknown MySQL server host '' (3)
My provider told me this is because omeka try to make the connection over MySQLi .
MySQLi needs the Portinformation as the 4. or 5. Parameter.
can you tell me how to arrange this?
thanks for your help.

Thanks to the guys from omeka we found the solution for this problem.

Zend_Db,don't supports port numbers in the hostname.

Looking at the initializeDb() function that begins on line 112 of
application/libraries/Omeka/Core.php (http://tinyurl.com/3usnab), it
looks like the port number is not being passed to the
Zend_Db::factory. (The $dsn variable also looks to be vestigial)

So first of all, db.ini needs the addition of :

port = "3307"

but in order for that to work, we need to add something like:

'port' => $db->port,

to line 128 of Core.php.

Is any of this on target Kris?

Details are on this page of the Zend
Framework docs:
