Wow, that seems premature.

The only sane thing to do with python is to bind to a particular version
at build time.   pkgsrc has been doing this for a long time, in that
there is python2.7, python3.4 but no bare python.   Thus each
python-using package can build against whatever versions work, and it's
all independent, except for some packages that have both prefixed files
(in /usr/pkg/lib/pythonX.Y) and globally-name files, and you can only
have one of those.

I am not clear on how gpsd deals, but it seems like the build should be
able to start off with a path to particular python version.
