Matt: Would you like to look at your buildbot to check if something is wrong with Tkinter? The code hangs on the CGMainDisplayID() call in support._is_gui_available(): from ctypes import cdll, c_int, pointer, Structure from ctypes.util import find_library app_services = cdll.LoadLibrary(find_library("ApplicationServices")) app_services.CGMainDisplayID()

Did some debugging by sticking a couple prints in support.is_gui_available() and it appears everything is fine up until the call to app_services.SetFrontProcess() -- this is returning error code -606 which is defined in: /System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/CarbonCore.framework/Versions/A/Headers/MacErrors.h: appIsDaemon = -606, /*app is BG-only, and launch flags disallow this*/ What this means exactly or how to fix it, I don't know...
