The problem is that we're trying to make a single build of matplotlib
that works with multiple different builds of Python, which might come
with different, incompatible builds of tkInter -- so if we build
against the version shipped with python A then it will be broken on
python B and vice-versa.

Or maybe not -- Matthew's seeing a segfault, and it *might* be due to
the existence of fundamental ABI incompatibilities between different
tk builds, but it hasn't really been characterized.

It might get backported to 3.5, maybe 3.4 if we're really quick, but
it won't get backported to 2.7, so yeah, anything involving changing
python upstream isn't going to be a short-term solution.
