Hi!

I’m trying to get the MAT.jl package to work but I’m unable to `]add` the latest versions of HDF5 and MAT. The latest versions at the moment are 0.11.0 and 0.5.0 respectively. Just doing `]add HDF5` installs the previous version 0.10.3. `]add HDF5@0.11.0` does the same thing.

My system:

```julia
julia> versioninfo()
Julia Version 1.0.2
Commit d789231e99 (2018-11-08 20:11 UTC)
Platform Info:
  OS: macOS (x86_64-apple-darwin14.5.0)
  CPU: Intel(R) Core(TM) i5-5257U CPU @ 2.70GHz
  WORD_SIZE: 64
  LIBM: libopenlibm
  LLVM: libLLVM-6.0.0 (ORCJIT, broadwell)

```

Has anyone an idea how to get it to work?
