This is my basic setup, which has jedi for Python working.

To complete the install of Jedi, do the following:

1.  Go into the elpa/jedi-yearmonthday-blah directory.
2.  make requirements
3.  sudo pip install -r requirements.txt

Jedi should work now with the included .emacs file.
Merge branch 'master' of github.com:tanglisha/emacs
