osx - 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 os x 10.9.1 . however, when launch idle running idle3 terminal, following warning shows in 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()" more information. >>> warning: version of tcl/tk (8.5.9) in use may unstable. visit http://www.python.org/download/mac/tcltk/ current information. 

why newer activetcl version have installed not recognized idle? how can rectify this?

edit: further details.

according "how python chooses tk library use" section of "idle , tinter tcl/tk on mac os x" page on official python website,

the python mac os x installers downloaded website dynamically link @ runtime tcl/tk mac os x frameworks. tcl/tk major version determined when installer created , cannot overridden. python 64-bit/32-bit mac os x installers python 3.4.x, 3.3.x, 3.2.x, , 2.7.x dynamically link tcl/tk 8.5 frameworks.

so seems that

1. the current python installations os x not recognize latest activetcl version (namely 8.6).
2. the tcl/tk version used python hard-wired during python installation procedure , cannot changed later.

from these observation solution clear:

1. install latest 8.5 activetcl version.
2. reinstall python.

i have followed these steps , seems work.
