 * 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

 * oops! in the second step, i meant you should edit /wordpress/wp-includes/wp-l10n.
   php
 * sorry!
