The first thing you should try is upgrading to the latest release candidate. See [this topic](https://discourse.julialang.org/t/julia-0-5-2-release-and-0-6-0-release-candidate-1-available/3630). FWIW, using this version `DataArrays.jl` loads on my machine using the latest RC and released packages, and tests run correctly.
