Note to save others from duplicating my silly mistake: although the filenames in this answer have a ".gz" extension, it is, in fact, necessary that the files be uncompressed before they are used. (There is a comment on the original website that could be interpreted to suggest otherwise.) If the first four bytes of the file are 0x1f8b0808 instead of 0x00000801 or 0x00000803, that means the file has not been uncompressed.
