error on 0.7 beta: ArgumentError: Package Statistics [...] is required but does not seem to be installed

[currymj]

I ran into this problem originally when trying to install DifferentialEquations.jl, but it seems to be an issue with this package. On trying to load the package I get an error around a "Statistics" package, which I'm unable to install separately using the package manager.

The beta won't work with most Julia packages. The nightlies has an update that fixes this and beta2 will be released soon since the beta is useless because of this stdlib issue.
