Has anyone tried to install VMWare Workstation from http://www.vmware.com/ ? I downloaded the latest version of Workstation .tar.gz and tried to install it on my Knoppix (hard disk installation) version 3.9. However it complains saying I don't have latest version of gcc or something.

So I thought to update my whole Knoppix, but apt-get update doesn't even work properly. It says it can't resolve/find certain URLs.
