Installed fine, works fine except that it won't restart; but that's a gksu issue.
Don't know if the following is a bug, or just normal operation:
When encountering an unmet dependency, if the user selects "cancel", all options (unmark, install, etc.) for that package become unavailable until "update" is chosen again. Seems to me the install option should still be available, and give the same result as the first time it was selected.
