wondering why planck in my travis build (ubuntu trusty) is failing: https://travis-ci.org/binaryage/env-config/builds/213516547 and it works as expected on my macOS 10.12 both running Planck 2.2.0, lumo works as expected on both systems

have to go, I will dig into it deeper when I get back, just wanted to ask if this could be a known issue

@darwin I'm not aware of any Linux-specific bugs for Planck. (Planck's unit tests run in Travis, FWIW.)

thanks
