And indeed they are. As you've probably noticed, I've mentioned
pkg/30029 and pkg/30030.

I don't know why -D doesn't reach the build for x11/gtk2, but for
pkg/30030, the intltool override was causing the problem. Could it be
something similar here? That one or more of the included buildlinks
override CPPFLAGS?
