gearhead binary package in Ubuntu Noble ppc64el

 A century and a half ago the Earth was nearly destroyed by nuclear
 war. Now, a federation of free city-states has begun to restore
 civilization. However, there are forces operating in the darkness
 which will unleash the horrors of the past age in a bid to determine
 the future of the human race.
 .
 Features of the game include random storyline generation, richly
 detailed character generation, complex NPC interaction, and of course
 over 150 different mechanical designs ranging from jet fighters to
 giant robots to city-smashing tanks.
 .
 This is the console version. For graphics, use gearhead-sdl instead.
