New issue 2125: Tcl doesn't work inside a virtualenv on Windows

Jens Diemer:

Using tkinter in virtualenv doesn't work with PyPy 2.6.0:

    c:/users/jens/appdata/roaming/dragonpy_env_pypy2/lib/tcl8.5 c:/users/jens/ap
pdata/roaming/dragonpy_env_pypy2/lib/tcl8.5 c:/users/jens/appdata/roaming/lib/tc
l8.5 c:/users/jens/appdata/roaming/dragonpy_env_pypy2/library c:/users/jens/appd
ata/roaming/library c:/users/jens/appdata/roaming/tcl8.5.13/library c:/users/jen

This probably means that Tcl wasn't installed properly.

It's a kind of a known bug, see: https://github.com/pypa/virtualenv/issues/93

Work-a-round is to set ```os.environ["TCL_LIBRARY"]``` see also: https://github.com/pypa/virtualenv/issues/93#issuecomment-132483445

I have done this to the right place: ```C:\\pypy-2.6.0-win32\\tcl\\tcl8.5```

But it seems that the pypy version didn't use this?!?
