That sounds like a good plan to me; I have no suggestions for changes
for environments for which I try to use or maintain gpsd packages. (I am
assuming that RPATH in scons leads to rpath args at link time.)

The only thing I think some others might want is a configure switch to
omit setting RPATH in scons build env, always.  But I don't know if that
is wanted by any actual people, and if so it's easy for them to send a
patch to add the switch.  And if the default is what you said, then I
can't see anyone else getting bothered by the new switch.
