I think expect is only required on the host you are running the installer from.
You can also try the 'graphical cross-platform installer'.
haha, ok I feel like an idiot now. Thanks for clarifying that.
Where can I get this 'graphical cross platform installer'???
the official release is w/ 7.4.1 i believe, unofficially talk to your local Bladelogic Consultant to see if this is an option for you all.
