file not found for module `montgomery`

This might be more user error than legitimate issue, but when trying to install aardwolf, I get this error:

` Compiling ring v0.11.0

However, arithmetic/montgomery.rs exists.

It looks like this is a known issue with a fix coming, but I don't have a solid enough grasp on Rust to fully understand what the issue is, exactly, or if there's a workaround in the meantime.

That's because the ring library doesn't use a proper directory structure, and it broke with versions of rust nightly newer that December 21st. Use an older version of rust and you should be okay. The Rocket developer is already aware and making a solution

thanks for the quick and simple explanation, @asonix!

Wait... I thought we Pinned the rocket version?

[BanjoFox]

In fact we did...
file: rust-toolchain

I am going to apply this update to the INSTALL.MD

Rocket works on the latest nightly again

Thanks @asonix - still wondering if it makes sense to pin a known-working nightly.
