[greg.barry]

It would appear that you do not have Compass/SASS installed on your machine. Or rather, Cmd cannot find your path to your Compass and SASS installations.

If you have not installed them, this is a helpful guide:
http://css-tricks.com/forums/discuss...-on-windows/p1

If you do have them installed, the above link also makes references to setting your paths.

Please keep in mind that earlier versions of the SDK tools did not require Compass and SASS.

Thanks!
Greg
