Phpopenchat installation error


I am trying to install PHPOpenChat on my shared hosting and when it get to the second installation step, I got the following errors:

Warning: Unexpected character in input: ’ ’ (ASCII=12) state=1 in /usr/local/dh/cgi-system/php.cgi on line 2788

Parse error: parse error, unexpected T_STRING in /usr/local/dh/cgi-system/php.cgi on line 2788

Can someone tell me what it means? I am not familiar at all with CGI.

Thanks for all your help.
