Line 12 in GLOBALS.php is:
$GLOBALS['INCLUDE'] = '/home2/bugladen/cake/tobacconerd/FUDforum/include/';
but line 117 is
It seems like 117 should be changed to
and this gets rid of the error I reported in the OP.
There are two other instances of $INCLUDE found using grep
./include/glob.inc: $stripped_globals = str_replace('require($INCLUDE .\'core.inc\');', '', $globals);
./src/post.php.t: $data = file_get_contents($INCLUDE .'theme/'. $usr->theme_name .'/usercp.inc');
