Does tcl/tk work? I.e., if you run wish or wish8.4, does it work? It seems that 
it can be a problem with a shared object used by libtk8.4.so that cannot be found.

You didn't compile your Python interpreter yourself, did you? The Setup file is 
in Python's source directory under the Modules directory. Open this file in a 
text editor and look for a line containing _tkinter. Read the comments after 
this line; they should be self-explanatory. If you modify the file, you'll have 
to re-compile your interpreter.

Maybe, maybe not... Apparently, the tk library is found, so Python seems to be 
correctly configured. Maybe the problem is in the tcl/tk installation, but you 
should see that by running wish.
