Failure with conda build rdkit in Linux

[yuj-umd]

I follow the instructions in https://github.com/rdkit/conda-rdkit/
But it constantly pumped out the error with

!!! TEST FAILURE: python PandasTools.py {}
!!! TEST FAILURE: python UnitTestPandasTools.py {}

98% tests passed, 2 tests failed out of 116

Total Test time (real) = 70.02 sec

The following tests FAILED:
111 - pythonTestDirML (Failed)
116 - pythonTestDirChem (Failed)
Errors while running CTest

Can someone help with it?
