AFAIK, there is no one working on gpsmon. Not for some time.
Do cgps and xgps work for you?
I don't have X installed, so I can only confirm that cgps does seem to work OK.
Are you 100% sure you totally removed all remnants of the previous
gpsd?
Yes, in the end I reinstalled the whole OS, and since then, I only installed version 3.20.
Plus I build gpsd with a build script, that generates an OS specific package, that I can install and remove at any later time, so I would rule that out as a possible cause.
I assume you recompiled on the RPi2? They are not binary compatible.
Yes, I absolutely did. Slackware on RPi1 was soft-float, and on RPi2 it's hard-float, so I had to do it.

What will show the problem is a gdb back trace.
Okay, I let gpsmon dump a core, but this time the binaries were stripped of debug information. If you'd like to see debug could you point me to some resource explaining how to do a debug-enabled build of gpsd with scons.

Sad, the startup is the most interesting part to me.
Okay, I can easily fix that. Please find the whole output attached.
Please let me know in case you need anything else.
