Failing to compile
I've cloned and tried to run
RUSTUP=0 make and encounter the following compile error:
>>> RUSTUP=0 make cargo +1.39.0 build --release error: no such subcommand: `+1.39.0` make: *** [Makefile:43: all] Error 101 Exception: make exited with 2 [tty], line 1: RUSTUP=0 make
Using rust and cargo version 1.39.0 on alpine linux.
