I get the following error when compiling any of the TFT/Arduino examples for either Zero or MKR1000
I do not get this error when compiling for UNO and similar
There are also some warnings that can probably be ignored.

Arduino IDE version 1.6.13 running on mac

csport = portOutputRegister(digitalPinToPort(_cs));

AND THE SAME FOR THREE SIMILAR LINES
rsport = portOutputRegister(digitalPinToPort(_rs));
clkport = portOutputRegister(digitalPinToPort(_sclk));
