With pkg-config 0.17.2, it is not possible to compile some software properly. The Requires: bit of the pc file seems to get ignored, and so libraries are missing on the link line. This happens trying to build evolution at least, while it is checking for palm pilot support. Doing pkg-config --libs gnome-pilot-2.0 doesn't list all of the libs that I would expect, either. And the errors in config.log are a multitude of undefined references while trying to test link the gnome-pilot libraries.
