[TYPO3-install] Dummy site install tool page showing empty

[HÃ¥kan Lane]

  I have been trying to install Typo3 together with Apache (httpd) on  
a Redhat server. After unzipping the source and dummy files, moving  
them to /var/www/html/ and changing permissions, I was supposed to  
access an installation page. It just shows up empty for me. The  
address is http://web.lmdg.econ.au.dk/typo3/index.php .
What should I do for the tool to show? Thanks in advance.
