I think I fixed this a few days ago.  Things go wrong if you include -lgps 
in the link switches for libgpsd.

I see 

    python_env = env.Clone()

which looks like it ought to bring in the flags from the main environment.
Are they getting dropped in some way?

I've seen the patch.  As you say, not ready yet, but I want full
coverage audiing to be part of our normal test routine someday.  So
please keep working on it.

Yeah, that one would be tough, because every test wants to emit a progress
spinner.  We'd have to emit some kind of fairly elaborate queue manager to
make this work.  I doubt the pain would be worth the gain.

It would.  We couldn't that have much explicit control of the configure 
output other than by heavily customizing the configure extension, though,
and that's another load of complexity I'm reluctant to take on.

Much more feasible.  http://www.scons.org/wiki/SconsAutoconf includes
some incomplete but suggestive documentation on how to do this.

That's probably the direction I'll go if I can't find a fix for the bug.
