Help with BinDeps

Hi,

I am facing issues with BinDeps and Gtk.jl. The issue is that under the latest ubuntu it asks for sudo although the required library libgtk-3-0 is already installed. Here is the build file:

https://github.com/JuliaGraphics/Gtk.jl/blob/master/deps/build.jl

Any help would be appreciated. Here is the output of BinDeps.debug("Gtk"). In my impression, all dependencies are resolved and its therefore not clear to be why it still tries to install libgtk-3-0

julia> BinDeps.debug("Gtk")
