Well, if anyone else runs into this, don't try using distcc unless all the other
machines are running the same .. everything.  In my case I was distcc to another
Slack11 box and a Ubuntu Edgy, and that seems to be source of my problem.

Also, I learned that omitting the CXX=distcc from the make line doesn't actually
stop distcc from distributing, you have to unset the DISTCC_HOSTS variable.

And, it turns out I was using the latest SVN, not the SVN for 0.20-fixes. 
Always something to learn.
