Cannot instantiate non-existent class: filereader

just a note that might help someone else:
i installed wp on a box with php 4.1 (ugh) and had to do 2 things to get it to run the install without errors:

1) create a blank file at /wordpress/wp-includes/languages/en_US.mo
(this prevents it from warning you that the file doesn’t exist)

2) in /wordpress/wp-includes/streams.php, i had to comment out the first if statement, resulting in the following code for lines 3-6:
//if ( defined('WPLANG') && '' != constant('WPLANG') ) {
require_once(ABSPATH . 'wp-includes/streams.php');
require_once(ABSPATH . 'wp-includes/gettext.php');
//}
(this is to prevent wp from a fatal error: Cannot instantiate non-existent class: filereader…)

i know that there may be problems implicit in what i’ve done and that the errors are symptomatic of a larger bug, but this seems to work for all intents and puposes until someone greater than i can isolate the real issue.

peace,
jim
