These are all legitimate and in my experience tend to come from trying to switch from building +x11 to building +quartz
without "cleaning the slate" as it were.  I always do this when switching like this (say with gimp2 that can build
either way).

sudo port install gimp2 (implied +x11 since it builds with x11 by default)
sudo port deactivate active
sudo port install gimp2 +quartz

This ensures that all the various sub-dependencies get built in the correct flavor.

Or install a separate MacPorts instance for building +quartz.  I've successfully done this as well.

I run into these issues alot with the GNOME ports because some GNOME ports can build +quartz but not all.  In
particular, ports that are part of the GNOME desktop infrastructure (e.g. gnome-desktop, gnome-settings-daemon) still
use X11 features directly and thus can't be built +quartz.  Others, like gcr, are just old implementations that use some
X11 hack instead of porting to a backend agnostic gtk3 implementation.

My general guidelines are this: if there is no +quartz variant, it builds with X11.  This includes ports with no variant
at all.  Only ports with +quartz variants should be assumed to build that way.
