Actually, you should only need new Mesa. The other bits should be fine.
./autogen.sh --enable-xcb --disable-glu --with-gallium-drivers=''
--with-dri-drivers=swrast,i965 --enable-texture-float --enable-debug
You don't have to install it, either. Just set these:
(obviously change the path)
Then, glxinfo ought to report something like:
OpenGL version string: 2.1 Mesa 7.12-devel (git-c916114)
