Tests fail on ubuntu

[tzhao42]

Do you want to request a feature or report a bug? Bug, make test fails right after installation.

What is the current behavior? Not all highlighting works as intended; dates and meta are not highlighted.

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem.

make
make install
make test
