rdkit build fail

[mark-str]

Trying to build RDKit and have got down to one failed test from six (improvement from adding pandas<0.2 to meta.yaml and using a Python 5.3 environment), but still have one failed test #111 'pythonTestDirML'.

Can anyone tell me how to solve it?

Currently using:
Python 3.5.4 :: Anaconda custom (64-bit)
conda-build 3.2.2
Ubuntu 16.04.3 LTS

Test output (all tests prior, pass):
