gpsdebuginfo alreay does this:

    head -n 1 `which xgps`

Your command assumes that the shebang is present and working.  And hides
valuable debug info.  gpsdebuginfo is for when things are broken.

The current test also prints gpsd module version, which may differ
from the python client version.  Which your does not do.

And, just today on IRC, a user wanted both python and python3, so best to
keep the script inclusive of options.

Assuming gpscat is not broken.  People run the script when things are
broken.

No way to know if python=no.  Worse, this will usually be run when
gpsd installed from packages.  It fails nicely, so I'm not worried about
running when not needed.  The problem is not being run when it needs to.

I changed the test from xgps to gpscat, as gpscat may be installed,
when xgps is not.
