# zlib not required because it is already part of OSX

# Travis-CI workaround

# When we install a package that is already installed inside the travis VM, and we have an outdated brew

# (for faster build), then we get an error and the build fails. Unfortunately brew doesn't have switch to skip

# already installed packages (https://github.com/Homebrew/brew/issues/2491) and recommends to install using

# brew bundle. But! `brew bundle` can't be run without updating brew and fails with error "Your Homebrew is outdated".

# Yep, i know what and this is what i want. So here is workaround: first we check which package is not already installed,

# and if not then install it.
