These should come from the Gtk+ implementation that is directly based on
Apple's Aqua/quartz libraries. This is highly experimental. The classic
way to run Gtk+ applications on Mac OS is to run them through the X11
application.

Of course, if you have binaries that rely on the experimental Gtk+Aqua
combination, then there's no way to use them without installing this. An
easier option might be to recompile your program using Gtk2Hs (possibly
from MacPorts).

Gtk+ can load all sorts of images, in particular jpeg images. Apple
seems to ship its own library called libjpg and MacPorts installs its
own in /opt/local. From our point of view, there's nothing we can do
about this, as this should be fixed in MacPorts. I think I did some
renaming on /opt/local/libjpg.dylib to get around this problem, which
isn't the right thing to do...
