conda updated yesterday and no longer works with blank versions, for example conda install numpy= produces a warning. This syntax was used to produce a "bleeding edge" build that would track the currently released NumPy, SciPy, etc.
conda install numpy=
This fix addresses the error in the 4th build so that syntax like numpy= is never used.

tests pass, but I didn't try to understand the change
Hmmm, I think I need to fix this. I think I have some wrong commits there for unit root.
Fix for conda 3.4 changes
More reasonable now.
Coverage remained the same when pulling 45aef53 on bashtage:travis-miniconda into 2762065 on statsmodels:master.
