Same problem here. The "Failed writing constant..." messages first then the "Parse error: syntax error, unexpected $end in... .../mainfile.php on line 32" error on the next screen when I try to install XOOPS 2.0.13.2

It's getting clear that I shouldn't use MySQL 5.x and/or PHP 5.x with XOOPS 2.0 but I'm just a geek and my Linux disto just put these two into my machine. Technically lame guys like me just can't change their MySQL or PHP version, and desperately need an XOOPS patch. If there is no a simple workaround for this problem I'll be very sad for leaving Xoops. :( :( Please help me!
