I have verified building from the .tar.bz2 file by doing:

tar -xjf MesaLib-8.0.tar.bz2
cd Mesa-8.0
./configure --enable-dri --with-dri-drivers=yes \
     --enable-gles1 --enable-gles2 --enable-glx-tls \
     --disable-glw --disable-glu --with-gallium-drivers \
     --enable-gallium-llvm
make -j6

I have also verified that I pushed all the cherry picks and the tag.
