xserver cannot compile with Mesa-6.5.2 sources

from xserver/GL/symlink-mesa.sh
----------
symlink_mesa_vbo() {
    src_dir src/mesa/vbo
    dst_dir mesa/vbo

    for src in $REAL_SRC_DIR/*.c $REAL_SRC_DIR/*.h; do
        action `basename $src`
    done
}
----------

There is no such directory in Mesa sources - vbo, xserver/configure script fails when running symlink-mesa.sh .
