Is there a problem that this fixes?

The problem with this change is the python package directory is
versioned by python version.  We don't want to install the same thing 7
places.

Part of the reason to do this is  to have one version that cares not
about python version.

Also, when installing a daemon only gpsd, there is no versioned
python directory yto install it in.

Is finding it a problem?  Seems to work fine now.

I'll look at it, but I'm not excited about it.

How do I see that?  I would like to be able to see that so the Pure Python
can confirm libgpsdpacket is the matching version.

Right, why do we care?
