As sometimes it is not set:

[28-Oct-2007 05:15:42] PHP Notice:  Undefined index:  HTTP_ACCEPT_ENCODING in /usr/share/mediawiki1.10/includes/OutputHandler.php on line 26

Simple fix

8<-----------------------------------------------------------
function wfGzipHandler( $s ) {
        if ( function_exists( 'gzencode' ) && !headers_sent() ) {
                $tokens = preg_split( '/[,; ]/', $_SERVER['HTTP_ACCEPT_ENCODING'] );
                if ( in_array( 'gzip', $tokens ) ) {
----------------------------------------------------------->8

SHOULD BE:

8<-----------------------------------------------------------
function wfGzipHandler( $s ) {
        if (isset($_SERVER['HTTP_ACCEPT_ENCODING']) && function_exists( 'gzencode' ) && !headers_sent() ) {
                $tokens = preg_split( '/[,; ]/', $_SERVER['HTTP_ACCEPT_ENCODING'] );
                if ( in_array( 'gzip', $tokens ) ) {
----------------------------------------------------------->8
