Cargo cann't download snapshot in msys2 and fails to build:

Here is a shell script that do same: https://gist.github.com/o01eg/1eedd5f49332113b9228

Ah it looks like https support isn't built in by default. I'd be fine going back to requiring curl to be installed to download the nightlies.

Isn't it better to remove python as dependency?

[alexcrichton]

It's a bit of a bootstrapping problem one way or another. We could rewrite the scripts in bash, but arguably python is a little more cross platform (thinking of windows), but requiring both would definitely be unfortunate!

I'm stuck with similar situation and am a newbie when it comes to command line scripts. I am using a mac with OSX. Below is the exact error I get when I run make. What should I do to get this up and running?
