The second README example fails

[ViralBShah]

The first one gives me a debug prompt now. The second example still seems to not work.

julia> using Gallium

Is it possible to have CI to auto test some of these things? Cc @tkelman

Probably not until it works on a non-source build of Julia. JuliaInterop/Cxx.jl#73 (comment) is where we left off with building custom binaries for Cxx, it needs Keno to rebase his LLDB branch so it isn't broken with gcc 5, or we need to update the buildbot configuration.
