It is always NULL. Looks like you haven't pushed all your changes:

grep -r blitFramebuffer *
plugins/opengl/include/opengl/opengl.h: extern GLBlitFramebufferProc blitFramebuffer;
plugins/opengl/src/screen.cpp: GLBlitFramebufferProc blitFramebuffer = NULL;
plugins/opengl/src/screen.cpp: if (!GL::blitFramebuffer)
plugins/opengl/src/screen.cpp: (*GL::blitFramebuffer) (src.x1 (), // sx0

And on that note, it appears GLXFramebuffer::blit is never called for some reason.
