Cannot Build HDF5 in 0.6.1

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.

Pkg.build("HDF5")

(another round of download attempts)

LoadError: None of the selected providers can install dependency libhdf5.
Use BinDeps.debug(package_name) to see available providers

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?
