Furthermore, X11 in Macports is getting some updates right now. I just introduced the system_x11 variant and will soon be moving all the ports to depend on port:xorg-libXXXX rather than lib:libXXXX:xorg-libXXXX. If you want to continue linking against the system X11, you should set the system_x11 variant globally. If you want to be extra careful and don't care about bloating your Gimp.app, you can first install the xorg-libs port and have your .app bundle the libs it needs.
and thanks for this hint. Just one more question? If I build GIMP.app on a Tiger machine and do not set system_x11, which X server will be used and how do launch it? As on Tiger or as on Leopard? (Ok, ok, two questions...) -skl
