This file should be copied to /usr/local/lib/dbus-1.0/include/dbus since 
it is architecture dependent. (different for x86_64 and x86 for example)

This ends up on the include path if you use the output of
"pkg-config --cflags dbus-1"

It is correct if you build with the output of
"pkg-config --cflags dbus-glib-1"

Possible (don't know if that code is up to date) but be sure you link
with "pkg-config --libs dbus-glib-1"

Normally pkg-config is used with backticks:

  cc -O2 -g -Wall `pkg-config --cflags --libs dbus-glib-1` foo.c -o foo

Note that ` is not the same as '

Or if you have autoconf set up, use the m4 macros that come with pkg-config.

The man page for pkg-config has some more detail, or look at pretty much 
any desktop-ish open source app's source code for an example.

pkg-config should probably be mentioned in the dbus docs somewhere if it 
isn't, but I guess it's just sort of assumed along with usage of the C 
compiler and so forth so nobody thought to mention it.
