matplotlib supports mathtext strings, like r'$\Phi_0 = e^{i\pi}$'. Currently,
if you want to mix mathmode and regular mode, r'for example: $\Phi_0 =
e^{i\pi}$', you need to enable usetex in your matplotlibrc file. usetex
requires latex, ghostscript, dvipng to be properly installed, see
http://www.scipy.org/Cookbook/Matplotlib/UsingTex for more details.

That's a new problem. Eric, it looks like some of your recent changes to
ticker.py had some unintended side-effects. Do you have time to look into it?
