Building 'ni' on ubuntu 10.10 and diamondback - can't find my libusb?

edit

I've been following along with the wiki: http://www.ros.org/wiki/ni

I've got diamondback, and my libusb is 1.0.8:

$ aptitude show libusb-1.0-0-dev
Package: libusb-1.0-0-dev                
State: installed
Version: 2:1.0.8-2

And then it dies on:

Any clue what I missed?
