Help with Cisco VPN Client

[BURMAT]

New here.. Just wanted to say this forum has provided me with so much help dealing with my problems. I just registered here because this is one problem I have not been able to solve by searching.

Before I am allowed to connect to my wireless here on campus, I have to download Cisco VPN client v4.6.00.045. The linux version of this is unsupported here though. I am running Ubuntu 9.04, GNOME 2.26.1, and Kernel 2.6.28-15-generic. I understand that there is a patch for Kernels 2.6+ but nothing seems to be working for me. I will post again the errors and everything I get from the failed install without the patch. Any help is greatly appreciated in advance.
