libgl1-mesa-dri-dbg 7.11-0ubuntu2 (armel binary) in ubuntu oneiric

 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 DRI modules.
