Kha: All I get is enigmatic "Haxe compiler error."

This is all I get when trying to build an empty project that I just created with: node /usr/local/lib/haxelib/kha/git/make --init

node /usr/local/lib/haxelib/kha/git/make html5
Creating Kha project.
Compiling shader 1 of 8 (painter-colored.frag.glsl).
Compiling shader 2 of 8 (painter-colored.vert.glsl).
Compiling shader 3 of 8 (painter-image.frag.glsl).
Compiling shader 4 of 8 (painter-image.vert.glsl).
Compiling shader 5 of 8 (painter-text.frag.glsl).
Compiling shader 6 of 8 (painter-text.vert.glsl).
Compiling shader 7 of 8 (painter-video.frag.glsl).
Compiling shader 8 of 8 (painter-video.vert.glsl).
Haxe compiler error.

When I try to run it with Kode Studio, with the github version of kha set, I get a similarly enigmatic output:

That’s it 😃

PS. I’m on Mac OS X El Capitan 10.11.6 if that matters.
