I have been trying to download use the `MAT` package. `Pkg.add("MAT")` works, but one of its dependencies, `HDF5`, does not install properly.
When I run `Pkg.build("HDF5")`, It can’t seem to find a place to download it.
```julia
Pkg.build("HDF5")

LoadError: None of the selected providers can install dependency libhdf5.

I am using windows 10, Julia 0.6.1, and have performed `Pkg.update()` to get all packages up to date.
Any help would be appreciated. Thanks.
Additional searching has led me to believe that `ttps://cache.julialang.org/http://download.opensuse.org/repositories/windows:/mingw:/win32/openSUSE_Leap_42.2/repodata/repomd.xml` may just be down. Is there any way for me to check this independently so that I can confirm this if a similar issue comes up again?

Update: Running `Pkg.build("HDF5")` worked today. It appears the OpenSuse server wasn’t responding. Does anyone have information on how `Pkg3` might address this?
