When started, the program consumes cpu time, but doesn't display anything. (Two arch testers have seen the same problem in bug 391469, but the package was stabilised in spite of this ...) Besides, there's no upstream any more (bug 208441), and the functionality is available in games-misc/xpenguins with "xpenguins --theme 'The Simpsons'". Maybe it would be best to remove the package.
