Travis CI fail: another problem with looking up openblas (#85)

876 -- A library with LAPACK API found.
786 -- LAPACK: 

...

1705 ImportError: /home/travis/miniconda/envs/test-environment/lib/python3.5/site-packages/slycot-0.3.5.11-py3.5-linux-x86_64.egg/slycot/_wrapper.so: undefined symbol: dgebal_
1706 The command "python Slycot/runtests.py --coverage --no-build" exited with 1.

There are also some alternative fixes in the conda-forge feedstock for Slycot.

I don't see anything in there that affects the TravisCI fail not finding it's openblas env on the CONDA=0 job.

#85 or #89 are the way to go.

All changes look good.
