If you install printconf-gui, but not alchemist and run printconf-gui, this happens: Traceback (innermost last): File "/usr/bin/printconf-gui", line 6, in ? import Alchemist ImportError: No module named Alchemist Install alchemist, and printconf-gui starts correctly. There is no dependency in printconf-gui to alchemist, when there should be. (Why printconf-gui isn't in the component list?)
