Tiger provides a version of cups that's too old. That's mentioned in the build instructions on GnomeLive. If you disable cups, then your users won't be able to print, so you should add a module to your project to build a more recent cups.

Interesting side-note: Apple seems to have become the principal developer of cups, and the OSX 10.8 developer release last winter included development snapshots that broke Gtk.
