Ok, on a fresh install (updated & Upgraded) of Intrepid:
I installed Superkaramba (revealed no dipendencies) and complained it needed Kross.
I installed the libkrosspython0 package (also revealed no dipendencies) it failed so I rebooted the virtual machine.
I am back at the needing PyQT missing but isn't bit.
