Hello

Attempting to run a new installation of Weewx 3.8.2 on OSX 10.13.6 High 
Sierra. Python 2.7.10. Weather station is an Acurite 5-in-1.

I can find some old references to libusb issues, but I did install libusb 
1.0.9. If the legacy version of libusb is still required I've not been able 
to find a package for it.

Installation followed was from weewx-3.8.2/docs/macos.htm where I had to 
make 2 modifications:

1) install pysqlite with the --user option

2) install Pillow instead of PIL 


Any insight is appreciated,
Thanks
Tom
