python-2.6.8-r1 builds and works fine with version 8.5 of both tcl+tk. When rebuilding with portage @preserved-rebuild feature, the 8.5 libs of both tcl and tk are preserved and used again when re-compiling python-2.6.8-r1. When you do a clean install with python-2.6.8-r1 with tcl and tk >=8.6, then it compiles fine, but is missing the _tkinter module. So as a workaround, until a real fix is around, i suggest to restrict the version dependency for both tcl and tk to <8.6
Well, this might have to do something with 8.6 not being listed in setup.py (detect_tkinter). It's listed in 2.7 - not sure, though, if other fixes necessary.

Please backport that fix instead of this version restrction. http://bugs.python.org/issue6244
