Sorry, I thought the clockmaker script was clear on that.  Please submit
a patch to the doc if you have a way to make that clearer.

Try not to confuse how you install and use gpsd with clockmaker, versus
the normal install and useage.

Yup.  And PYTHONPATH gets folded into sys.path.  So the way a user
adjusts sys.patch is with PYTHONPATH.

Lost me.  There is no waf/python.

When you run a python program in the location that clockmaker tells you to,
then the gps is in that directory (.), which is in sys.path.

Easy to see you sys.path:

    $ python
    Python 2.7.15 (default, Sep 12 2018, 11:58:35) 
    [GCC 8.2.0] on linux2
    Type "help", "copyright", "credits" or "license" for more information.
    >>> import sys
    >>> sys.path
    [...]
