The problem with simply removing

pkgconfig_RUN_DEPENDS=          pkg-config:${PORTSDIR}/devel/pkg-config

from bsd.gnome.mk is that there are ports that indirectly depend on pkg-config 
for their build through other ports that directly depend on it since it has 
just been a runtime dependency.  I know there are quite a few KDE ports like 
that.

To explain better, x11/kdelibs4 has USE_GNOME=pkgconfig, but some ports that 
depend on kdelibs4 and require pkg-config for their build are not currently 
defining USE_GNOME=pkgconfig since it is assumed that pkg-config is installed.  
A direct dependency for pkg-config would need to be added to all of those 
ports.

I think there would be a lot less breakage if the line in bsd.gnome.mk were 
left in for now and we migrated over to the pkgconfig:build/run scheme.
