Isn't that fun? Mac fixed their readline.c for maverick and as a result the patches in python segfault now – yay. In order for python to work, you need to install the latest rc1 of python3.3.3, also not public yet. So if you run into that problem, here is the link to install:

http://www.python.org/download/releases/3.3.3/

Don't forget that a) that maverick resets the third-party-app-security setting and disallows your pkg to be installed (change it at "System Settings -> Security -> General") and b) the interpreter is called python3.3 (as it isn't overriding the default python).
