libgl1-mesa-dri-experimental-dbg 8.0.2-0ubuntu3 (powerpc binary) in ubuntu precise

 This version of Mesa provides GLX and DRI capabilities: it is capable of
 both direct and indirect rendering. For direct rendering, it can use DRI
 modules from the libgl1-mesa-dri package to accelerate drawing.
 .
 This package does not include the OpenGL library itself, only the DRI
 modules for accelerating direct rendering.
 .
 For a complete description of Mesa, please look at the
 libgl1-mesa-swx11 package.
 .
 This package contains debugging symbols for the extra DRI modules.
