Installing Elixir on an Nvidia Jetson Nano development board

I am attempting to install Elixir on an Nvidia Jetson Nano development board. This board runs ubuntu 18.04 LTS, on a 4-core ARMv8 rev 1 (v8l) processor. I’ve attempted to install using the distributions, then precompiled packages, and then compiling from source. Erlang/OTP 20 seems to install OK, following the instructions for the ubuntu distribution, but then continuing it installs elixir 1.3.3. iex works, but elixir --version terminates abnormally.
Any help appreciated!
