 Now, we can install Python 2.7: ::
 
-    $ brew install python --framework
-
-This will take a minute or two. Once that's complete, you'll have to add the
-new Python scripts directory to your ``PATH``
-
-.. code-block:: console
-
-    export PATH=/usr/local/share/python:$PATH

-The ``--framework`` option tells Homebrew to compile a Framework-style Python
-build, rather than a UNIX-style build. The outdated version of Python that

-some future module installation bugs.
