Install failing on macos [missing linux/spi/spidev.h]

[M.Griffiths]

i tried installing spidev on macos and the issue seems to be with missing header files. I have xcode and gcc installed so I'm not sure how to get the missing header file. linux/spi/spidev.h

This library is a python wrapper for linux spidev. Mac does not have spidev, so installation on a mac is not supported.
