Tkinter - fails in a virtual env #56
Description
When a virtualenv which shares the global environment site-packges is used for Tk based application using the global Tk.
Tkinter cannot initialise correctly in a virtualenv as it fails to correctly search for it's resources - which are still in the global python environment.

_tkinter.TclError: Can't find a usable init.tcl in the following directories:

ary c:/library c:/tcl8.5.2/library c:/tcl8.5.2/library
This probably means that Tcl wasn't installed properly.

What I would expect is for a virtual env to work the same as the globale environment like so:--
C:\venvtest>c:\Python26\python.exe

>>> import Tkinter
>>> f = Tkinter.Tk()
>>> ^Z
C:\venvtest>
After some experimentation I have found that copying c:\python26\tcl{tcl,tk}8.5 directories into the c:\venvtest\Libs solve the issues.
