Hi! Is it possible that some locations changed in your installation? Here is an old post that has a very similar error: https://groups.google.com/forum/#!topic/sage-support/fV2VNL-5UuY
Otherwise, perhaps the problem may be the one described here: http://ask.sagemath.org/question/626/sage-python-import-matplotlib-no-module-named in which case the binary was probably compiled without tkagg support, which is normal. You could Compile Sage from scratch, perhaps could redo matplotlib. See also http://ask.sagemath.org/question/3962/gui-backend-matplotlib-in-sage Now, we did upgrade matplotlib in http://trac.sagemath.org/ticket/14993 so I wouldn't be surprised if that did cause some problems (there were several tickets fixed) but it is a little surprising that this is the one, since we have this same line in the documentation at http://www.sagemath.org/doc/reference/plotting/sage/plot/plot.html#sage.plot.plot.SelectiveFormatter I hope that ONE of these things helps, but I'm sorry if not - in that event, any other platform details would be very helpful for us.
