I'm simply separating out daemon.c from libgps sources list
 and since it's not used by libgpsd either, it's put into a new sources list:

# Sources used not only by gpsd itself but also other production programs
misc_sources = [
    "daemon.c",
]

static_misclib = env.StaticLibrary(target="misc_static",
                           source=[env.StaticObject(s) for s in misc_sources])

Then only programs that potentially use it (rather than a system detected 
version) include this in their linking list, e.g.:

gpspipe = env.Program('gpspipe', ['gpspipe.c'],
                      LIBS=['gps_static', 'misc_static'], LIBPATH='.',
                      parse_flags=gpsflags)

Rather than the more extensive changes Fred is proposing.
