when trying to install minitest when branch is omitted. if I add branch:master it installs the dependencies.

Shards should fetch master branch if not specified.

I'm on Debian 4.7.2-5 , x86_64

[ysbaddaden]

It defaults to install the latest version since the default version requirement is * and eventually fallback to HEAD. But this isn't the issue here.

The bug is actually located in the NaturalSort helper —which must be failing since Crystal 0.7.4.

Thanks for reporting, this is now fixed!
