Review comment:
@gigasquid happy to try to do that! i haven't ever used Clojure or Scala
before. But I've run into a problem even getting the first step, `make
scalapkg`, to work on macOS. The make initially failed, comlpaining it couldn't
find the mvn executable. I assumed that was maven, `brew install maven` had me
first `brew install java`. Then `make scalapkg` seemed to be happy, and
downloaded a bunch of stuff (including scala). But it failed with this:

This seems to be related to https://issues.scala-lang.org/browse/SI-9103,
but that issue is still open. I have no idea whats going on or how to make
progress. I reran the `make scalapkg` to no effect, here's a gist with the full
output: https://gist.github.com/taliesinb/d0f09e9f0202c3983298511383542f59. Do
you have any suggestions?
