Issue #15663: Revert OS X installer built-in Tcl/Tk support for 2.7.6.
Some third-party projects, such as matplotlib and PIL/Pillow,
depended on being able to build with Tcl and Tk frameworks in
/Library/Frameworks. They were unable to build with the built-in
Tcl/Tk and/or execute correctly.

-Installing a third-party version of Tcl/Tk is no longer required

-As of Python 2.7.6, the 10.6+ 64-bit installer now
-comes with its own private copy of Tcl and Tk 8.5 libraries. For
-this version of Python, it is no longer necessary to install
-a third-party version of Tcl/Tk 8.5, such as those from ActiveState,
-to work around the problematic versions of Tcl/Tk 8.5 shipped by
-Apple in OS X 10.6 and later. (This does not change the requirements
-for older versions of Python installed from python.org.) By default,
-this version of Python will always use its own private version,
-regardless of whether a third-party Tcl/Tk is installed.
-The 10.3+ 32-bit-only installer continues to use Tcl/Tk 8.4,
-either a third-party or system-supplied version.

+To use IDLE or other programs that use the Tkinter graphical user
+interface toolkit, you may need to install a newer third-party version
+of the Tcl/Tk frameworks. Visit http://www.python.org/download/mac/tcltk/
for current information about supported and recommended versions of
Tcl/Tk for this version of Python and of Mac OS X.
