When I run\n\n```\npython3.4 -c \"import matplotlib; matplotlib.test()\"\n```\n\nI get 4 tests in error (see below).\n\nTo reproduce, check out https://github.com/andrewclegg/snake-charmer/commit/72734deb5b3a5d9cf4848aeb6b19a4661a85efe7, spin up a VM as directed in the [README](https://github.com/andrewclegg/snake-charmer/blob/72734deb5b3a5d9cf4848aeb6b19a4661a85efe7/README.md), log into the VM by doing `vagrant ssh` and run the tests as normal.\n\nTest
