wp-config.php

I install WordPress from scratch using the version in the CVS. I made a copy of wp-config.php from wp-config.sample.php. However, I found out there is an error in wp-config.php as the installer cannot find the file day-month-trans.php.
I did the following:
Open the file wp-config.php and comment out line 42, which is:
require_once(‘day-month-trans.php’);
After line 53, which is:
$abspath = dirname(__FILE__).’/’;
Insert the following:
require_once($abspath.’/day-month-trans.php’);
The installer completes with no error. However, I am not sure if this fix has other impacts on other files.
