Unfortunately the zip extension is used for a bunch of different compression programs, not all of which are 
interoperable. Stick to tar.gz.

Equally unfortunately, jhbuild insists on first decompressing then unarchiving gzipped tarballs when tar is 
quite capable of doing so itself. That said,
I downloaded SDL2_mixer-2.0.1.tar.gz and MacOS Sierra’ gzip had no problems with it. I got a sha256 of 
5a24f62a610249d744cbd8d28ee399d8905db7222bf3bdbc8a8b4a76e597695f (use shasum -a 256 to check your download). 
You can work around the problem on your own system by simply untarring SDL2_mixer to the appropriate source 
directory by hand then tell jhbuild to ignore the error and proceed to configure.
