I'm not too worried about being a few versions behind as long as it's not  
the direct cause of the PPS issues I'm running into. OTOH, as Jessie is on  
3.11, I notice that PPS support was marked experimental until 3.12. So I  
guess it might be worth trying to compile a more recent version from  
source.

Have you had a chance to evaluate the debug output I provided? I've  
repasted it below my signature in this e-mail for your reference. Recall  
that ppstest is able to get valid data from /dev/pps0, but the output  
below indicates that gpsd is not managing to open /dev/pps0 successfully.  
Both ppstest and gpsd are being run as root, so permissions shouldn't be  
an issue.
