Additional Information

Probably a side effect of the migration to CMake'ified python.
I was able to reproduce the problem. Travelling this weekend, will be addressing this next week.
Make sure to create an issue and assigned it to me.
Thanks

It turns out that the python extension are not properly fixed up. As illustrated below, the path is:

@executable_path/../../Contents/MacOS/<PythonExtension>.so

whereas it should be:

@executable_path/../../Contents/lib/Python/lib/python2.7/lib-dynload/<PythonExtension>.so

Output of otool:

factory-south:lib-dynload kitware$ otool -L _tkinter.so
_tkinter.so:
@executable_path/../../Contents/MacOS/_tkinter.so (compatibility version 0.0.0, current version 0.0.0)
@executable_path/../lib/TclTk/lib/libtcl8.4.dylib (compatibility version 8.4.0, current version 8.4.19)

While it could be problematic not to have properly fixed up extension, this is a different issue but not the source of the current problem.

The problem was that the "lib-tk" path wasn't appended to the PYTHONPATH definition while compiling getpath.c (unix) or getpathp.c (windows)

Topic "add-lib-tk-to-pythonpath" should fix the issue and is currently being tested.

Topic fixed tcl test associate with CMake'ified python. See http://open.cdash.org/buildSummary.php?buildid=2877484

Local build of slicer including the change allow to import Tkinter :) External_python.cmake will be updated soon.
