@lucagiovagnoli That's just on your Mac, I suspect (dmlc/xgboost#1776). Travis CI just shows a couple of failing tests.

@talalryz @voganrc what are your thoughts on this PR? do you want to try the upgrade to 1.1.1 or should we close it for now?

[ancasarb]

Closing for now, can reopen if/when needed.
