Comment 4 for bug 1284190

Maybe latest OpenSceneGraph 3.2.1 release would compile in Ubuntu (GLES) - I've found some fixes related to GLES2 in 3.2.1rc2 Changelog:

2013-10-01 09:05 robert

 * src/osg/PointSprite.cpp: From Thomas Hogarth, "Attached is a
   small build fix for PointSprite when compiling under GLES2
   (r13788)

   GL_POINT_SPRITE_OES does not exist in GLES2, instead you just
   draw using GL_POINTS then use gl_PointSize in a vertex shader to
   set the size."
