Since the size of the mac dmg came up the other day I decided to figure out where some of that growth came from. Attached is a chart of the installed size of the various modules that get installed into the runtime; this is linux build data but the mac build should be roughly analogous (though it doesn't include R). Units of size is MB. the python and perl runtime_1 components are the core interpreters; the runtime_2 components are the module collections that are installed. --bob
