Help!! Please install RPM package pygtk2 >= 2.0

[d1726]

When I try to install Scalix on a core 4 server I get this error:
Scalix Installer - extracting archive, please wait...
Scalix Installer - starting version 10.0.1.24...
Scalix Installer - using Python 2.4.3.
Error: 'No module named pygtk'.
Please install RPM package pygtk2 >= 2.0. This package can usually be found on the distribution CD or on the vendor web site.
Scalix Installer - cleaning up...
Scalix Installer - stopped.

But when I enter rpm -qa | grep pygtk I get the following
pygtk2-debuginfo-2.8.5-0.gst.1.4
pygtk2-2.6.2-0.fc4.4
pygtk2-libglade-2.6.2-0.fc4.4
pygtk2-devel-2.6.2-0.fc4.4
pygtk2-2.0.0-1 (forced the install of this to fix problem, did not work)

I have tried serveral different things to fix the issue but none have worked, I have ran all the updates, issued the updatedb command, now I am just stuck. Can anyone help

Probably the fastest way around this is to install via the Command Line Interface. Type:

./scalix-installer --cli

Thanks,
