prboom 2:2.4.7+dfsg-2 (ia64 binary) in ubuntu intrepid

 Doom is a 3d shoot'em'up game, written by id Software, first
 released in 1993.
 .
 PrBoom is a version of Doom using the Simple Direct Media
 layer (SDL) library, which enables it to use XFree86, OpenGL,
 Linux framebuffer console, GGI, SVGALib or even color or
 monochrome text consoles as display. There is an additional
 OpenGL renderer as well.
 .
 PrBoom is based on MBF and LxDoom, which in turn are based on
 Boom, a freely available port of Doom for DOS, written by
 TeamTNT (http://www.teamtnt.com/).
 .
 PrBoom requires an IWAD to play. A free IWAD is available
 in the freedoom package. You can install your commercial
 Doom IWADs using doom-package.
