[BLUG] Can't Connect to IU VPN in Ubuntu

I am trying to connect to the IU VPN in Ubuntu using the USSG script found here:  http://www.ussg.iu.edu/support/documentation#iuvpn  I believe I've installed all the requirements listed on that page and I also think I'm following the directions correctly, but something isn't quite right as I can't connect.  I am connecting with my pc and its wired connection and I can connect to the VPN from Windows with no problem.  Here's what happens when I run the script:

Have I missed a crucial step somewhere?  I'd really appreciate any help you can throw my way.
