This happens from time to time on the 10.6 builders only, after they have been online for awhile. I don't know why; I suspect a bug in the OS or in that version of Xcode, which will of course never be fixed. I've rebooted the builder, which should take care of the problem for now. 

I've triggered a new build of gtk3. If any other ports failed to build because of this, please trigger new builds.
