`take` is deprecated on Julia master but not 0.5. Unless you have a
good reason to run Julia-master, you should use the current stable
release Julia-0.5 where `take` is not deprecated. Also note that
packages will likely not keep up to date with Julia-master. Thus if you
do use Julia-master expect breakages going beyond deprecation warnings.
Anyway, the deprecation warning should tell you where it was triggered.
Although sometimes that fails, then you have to narrow it down with the
usual debugging techniques.
