Issue downloading and installing Rmath on windows

[pclausen]

During installation of Gadfly I got this following error.

The workaround was to download the file
https://github.com/JuliaLang/Rmath-julia/releases/download/v0.2.0/libRmath-julia-win-x86_64-v0.2.0.zip and put it into %HOME%.julia\v0.6\Rmath\deps\downloads then run
Pkg.build("Rmath")

Sounds related to JuliaLang/julia#26167.

@nalimilan No, I had the same problem but got it fixed it with the mentioned "Easy Fix". Before that got fixed, NOTHING worked, not even Pkg.update() on a clean install. So I believe this problem is related to the download of the zip file (which is weird because all others packages could download without issues....).

I think it's due to GitHub requiring TLS 1.1+: Rmath is one of the few package binaries which is actually hosted on GitHub (I think most other use openSUSE).

[simonbyrne]

Should be fixed now by JuliaPackaging/BinDeps.jl#354
