Table Prefix doesn't work

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Add a tables_prefix in config
2. Install
3. Try to log in

What is the expected output? What do you see instead?
A login screen is expected, but the install screen is shown
error: BASE_URI

What version of the product are you using? On what operating system?
r561

Please provide any additional information below.
In the code all db queries include the default 'tbl' prefix, see f.i. 
/includes/site.options.php line 18

In my logs I get an error like this:
 File does not exist: .../httpdocs/filemanager/install/BASE_URIincludes, referer: .../filemanager/install/index.php

The default tabel prefix has to be set as tbl_ or it breaks for some reason.
**define('TABLES_PREFIX', 'tbl_');

After the config file is set, you have to run the INstall page the first time.

Sorry, the tables prefix config is not implemented yet.
It's a placeholder. This is something I'd like to finish for the next release. 
Sorry!
