Above installs mruby but I still need to copy binaries, include path and libs into the store to make it work. Should be fairly trivial.

You can build mruby in a GNU Guix container with

~/.config/guix/current/bin/guix environment -C guix --ad-hoc ruby bison

Tests pass without network access

>>> Test test <<<
mrbtest - Embeddable Ruby Test
