It looks like Anaconda no longer installs the `mpl_toolkits` module (which installs `mplot3d`) by default when you install `matplotlib`, at least on on some systems.

I just ran into this problem on Windows: I had to do `using Conda; Conda.add("basemap")` to install `mpl_toolkits`, which forced a downgrade of the numpy package.

Probably PyPlot should be updated to work (with 3d plotting disabled) if mplot3d is not available.
