IDLE warns against an old TCL version even though I've installed a newer version

I have installed ActiveTcl8.6.1.1.297588-macosx10.5-i386-x86_64-threaded on my OS X 10.9.1 . However, when I launch IDLE by running idle3 from the terminal, the following warning shows in the IDLE window:

Python 3.3.3 (v3.3.3:c3896275c0f6, Nov 16 2013, 23:39:35) 
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
Type "copyright", "credits" or "license()" for more information.
>>> WARNING: The version of Tcl/Tk (8.5.9) in use may be unstable.
Visit http://www.python.org/download/mac/tcltk/ for current information.

Why is the newer ActiveTcl version that I have installed not recognized by IDLE? How can I rectify this?

EDIT: Further details.

According to the "How Python Chooses Which Tk Library To Use" section of the "IDLE and tinter with Tcl/Tk on Mac OS X" page on the official python website,

The Python for Mac OS X installers downloaded from this website dynamically link at runtime to Tcl/Tk Mac OS X frameworks. The Tcl/Tk major version is determined when the installer is created and cannot be overridden. The Python 64-bit/32-bit Mac OS X installers for Python 3.4.x, 3.3.x, 3.2.x, and 2.7.x dynamically link to Tcl/Tk 8.5 frameworks.

So it seems that

  1. The current python installations for OS X do not recognize the latest ActiveTcl version (namely 8.6).
  2. The Tcl/Tk version used by python is hard-wired during the python installation procedure and cannot be changed later.

From these observation the solution is clear:

  1. Install the latest 8.5 ActiveTcl version.
  2. Reinstall python.

I have followed these steps and now everything seems to work.

I have OS X 10.10.5.

  1. I installed Python 3.4.3.
  2. Ran IDLE, got warning, "The version of Tcl/Tk (8.5.9) in use may be unstable."
  3. Went to [Active State][1] and downloaded the suggested, "Download ActiveTcl 8.6.4 for Mac OS X (10.5+, x86_64/x86)".
  4. Ran installer for "ActiveTcl8.6.4.1.299124-macosx10.5-i386-x86_64-threaded.dmg"
  5. Re-installed: python-3.4.3-macosx10.6.pkg
  6. Ran IDLE - still same message, "The version of Tcl/Tk (8.5.9) in use may be unstable.".
  7. Checked - Yes, 8.6.4 is there.
  8. Went back to Active State and got prior version: "ActiveTcl8.5.18.0.298892-macosx10.5-i386-x86_64-threaded.dmg"
  9. Re-installed: python-3.4.3-macosx10.6.pkg
  10. Ran IDLE - No warning.

This worked for me

WARNING: The version of Tcl/Tk (8.5.9) in use may be unstable.

brew remove python3

brew install homebrew/dupes/tcl-tk

brew install python3 --with-tcl-tk

brew linkapps python3
