The package tests pass on my machine, but the Travis build seems to be failing with some error related to the installation of the matplotlib dependency. I googled it and came up empty. Is there a bug in the Julia environment on Travis, or am I doing something wrong?

That made it run, thanks. Now I have to fix the test timing out issue.
