Unable to install the Netjuke on RedHat 9

Hello All,

I just installed Red Hat 9 and trying to install Netjuke. When I try to 
access the installer.php via Mozilla browser 1.8a3 and the default php was 
loaded during the installation is:

# rpm -qa | grep php
php-ldap-4.2.2-17
php-imap-4.2.2-17
php-4.2.2-17

I am getting the following errors:

BROWSER VERSION ERROR

Browser:

Sorry, but you cannot use Netscape 4.x (or lower) to install the netjuke 
because of major javascript compatibility issues.

Please use the Open-Source Mozilla, or Netscape 6, or MS Internet Explorer, 
or Konqueror, etc.

Sorry for this limitation, and thank you for trying and / or using the 
Artekopia Netjuke
