How to build and install
The following shows how to get the latest code from libubuntuone trunk, configure to install system wide, and then install. Most will be building libubuntuone to use with Rhythmbox in order to test the Ubuntu One Music Store plugin so once the steps below are successful you should be able to open Rhythmbox and access the Ubuntu One Music Store using the latest and greatest libubuntuone.
Only need to do this once. If there are dependencies you find are missing from here, please add.

Checkout, configure, build, install
