I just had a look at the INSTALL docs on the release version, it says "If 
you are on the RasPi with gpsd version 3.17, or above, /dev/pps0 can be 
autodetected. and used for PPS if available." So that would explain why 
gpsd works fine on my other two raspi's, without /dev/pps0 declared...

The INSTALL file needs an update - it still talks about Debian Wheezy, and 
refers to Debian Jessie as the current release. I'll see about sending in 
updates.

I'm going to rebuild gpsd from release, maybe it actually is something 
there...

...and rather than draw out the discussion, I downloaded the release 
version, built it with identical scons options, and poof - instant SHM(0) 
PPS output.

Oh well, go figure. I'd be surprised if this was a bug in that particular 
git release - I'm suspecting that I may have had the UART settings gummed 
up before building gpsd, and for some reason the built code couldn't grok 
PPS - even though the gpsd -h output said it was enabled. Maybe.

Thanks for the help - as well thanks to Hal for his notes, too many sanity 
checks is never enough.
