Hello,

Since version 3.27.0 of liblouis, the liblouisutdml testsuite doesn't pass any more:

FAIL: test_mathml_woluwe/test_001
=================================

FAIL test_mathml_woluwe/test_001.test (exit status: 1)

And similarly for various other tests

(This is preventing that version of liblouis from entering Debian)

I believe this bug has been fixed when merging #99
