I have been trying to use Rustup for a while now and it says this when I try to do anything with it:
info: caused by: [1] Unsupported protocol (Protocol "https" not supported or disabled in libcurl)
I know that cURL has HTTPS enabled — I just tried using it and it worked fine.

Probably not what you want to hear, but they have known issues at the moment with ARM.
This workaround seems to work for me:
- Directly download rustup-init from https://github.com/rust-lang-nursery/rustup.rs for your platform
env RUSTUP_USE_HYPER=1 ./rustup-init
It should also work to export RUSTUP_USE_HYPER=1 (assuming you aren't using tcsh) before running the rustup script, but the above is what I tested and used.
