My apologies, that guide is apparently grossly outdated... SPI is definitely supported in the Arduino IDE at this time, however the Leonardo has SPI connected only to the ICSP header and any shield that does not derive SPI from the ICSP header (i.e., CAN BUS Shield) will not work stacked. You can use jumper wires and get it working.
