Suite Install.php fails to run

[محروم.كوم]

Hi folks*

I just purchased the 4.0 Publishing Suite. Edited config.php & uploaded "upload/" to my server. Went to http://domain.com/install/install.php and got a "500 Internal Server Error" so I ssh'd in and tried to run the file manually:

Code:
# ./install.php
./install.php: line 1: ?php: No such file or directory

./install.php: line 4: syntax error near unexpected token `||'
./install.php: line 4: `|| # vBulletin 4.0.0 Patch Level 1 - Licence Number VBSB4A54A8'
What's wrong? PHP & mySQL versions:

Code:
# php -v
PHP 5.3.0 (cli) (built: Sep 27 2009 16:15:37)
Copyright (c) 1997-2009 The PHP Group
Zend Engine v2.3.0* Copyright (c) 1998-2009 Zend Technologies

# mysql -V
mysql Ver 14.12 Distrib 5.0.27* for pc-linux-gnu (i686) using readline 5.0
