+and out comes a full-featured MacOS application.  BuildApplet.app is now
+deprecated and has been removed in Python 3.  As of OS X 10.8, Xcode 4 no
+longer supplies the headers for the deprecated QuickDraw APIs used by
+the EasyDialogs module making BuildApplet unusable as an app.  It will
+not be built by the Mac/Makefile in this case.
 
 The commandline scripts /usr/local/bin/python and pythonw can be used to run
 non-GUI and GUI python scripts from the command line, respectively.
