No need for a URL, all you need is in the INSTALL file in the gpsd
tar ball.  Just search for RasPi.

That would be a good PPS.

You probably do not have KPPS in you kernel.  You probably need to compile
a new kernel as described in the 'gpsd-time-service-howto.txt' in the
gpsd tar ball.

Those messages are not from gpsd.  Note that they have the prefix 'kernel:'.

They show that you have KPPS in your kernel.  So if gpsd is not
seeing them then you missed the steps in the INSTALL file that
tell how to tell gpsd to find the right /dev/pps.

No, just the same ones, read the INSTALL and gpsd-time-service-howto.txt
files that are in the gpsd tar ball.  Paying particular attention to the
parts marked as RasPi.
