I followed instructions for avr-rust and blink compilation. But I am getting this error:

$ rustup run avr-toolchain xargo build --target avr-atmega328p --release
   Compiling core v0.0.0 (/data/projects/rust/src/libcore)

I'm using Mac and I used latest version of avr-rust from avr-support branch (cea79f77f5eac).
