Excellent.

Yes.  I repaired the DBUS build (there was a tracker bug about this).
That message means that your build found and linked the dbus-1
libraries but that gpsd could not raise DBUS on startup.

In theory, yes.

I saw a debug message that was indicative of a version of the packet
getter from before I got EOF injection quite right.  (It was from the
logic tracking average packet traffic per second, part of the
discarded adaptive-delay code.)

Apparently.

    if env["shared"] and env["chrpath"]:
        if WhereIs('chrpath'):
            # Tell generated binaries to look in the current directory
            # for shared libraries so we can run ad-hoc tests without
            # hassle (the regression tests *don't* need this as
            # they're run in a controlled environment where we can set
            # LD_LIBRARY_PATH). Should be handled sanely by scons on
            # all systems.  Not good to use '.' or a relative path
            # here; it's a security risk.  At install time we use
            # chrpath to edit this out of RPATH.
            env.Prepend(RPATH=[os.path.realpath(os.curdir)])
        else:
            print "chrpath is not available; please build with chrpath=no."

I'll test here and on tom.
