I'm already using the latest changes from the Hg repository.  Yes, I
already have built the latest dbus (and libevent) which adds its (their)
.pc files and the Qt project uses the correct pkg-config with the
correct path.

I found the root of my problem, the project's .pro file had a generic
addition (i.e. somebody put an INCLUDEPATH) which added the
/usr/include.  The other problem, g++ 4.5.2 searching the headers in
different order, I haven't researched.
