Rust and FreeBSD

[josejachuf]

Rust-dependent packages do not download compiled, download and compile at the moment
For those who want to use emmett-crypto in FreeBSD, they must do the following:

1. Install Rust:
   pkg install rust
2. Install emmett-crypto
   pip install emmett-crypto

Another example is orjson dependence, it is compiled at the time of installing

pip install orjson

Maybe you have to set the environment variable

setenv RUSTC_BOOTSTRAP encoding_rs

I hope this can be helpful
