But I do get the following message at the end of the `GTK` and `Cairo` install:
objc[49750]: Class GNotificationCenterDelegate is implemented in both /Users /ortner/.julia/v0.5/Homebrew/deps/usr/opt/glib/lib/libgio-2.0.0.dylib and / usr/local/opt/glib/lib/libgio-2.0.0.dylib. One of the two will be used. Which one is undefined.
