you might wanna try to set PKG_CONFIG_PATH to make it find the needed
bluez.pc file. Check "man pkg-config" for more details.

If these libraries are not found, none of them get build. You might see
make entering these subdirectories, but that's it.

It is more than simple notification thingy. You can control all needed
functionality. And this is why it is 3.x now and no longer 2.x.

Then go with expat. It is small and lightweight.

Nobody said, that it is easy, but even the Nokia 770 for example is
happy with D-Bus and I know that a lot of embedded people actually use
D-Bus instead inventing a message bus over and over.
