Error when starting KaShell language

Error when starting KaShell language

[Jason Hemann]

Hi all,

I wanted to play with the KaShell language (http://kashell.org/), and I
believe I followed the instructions to start. However, I see the following
error message when I try:

````
bash-3.2$ bash --version

I'm new at using Kawa, so this could easily be some simple setup or
configuration error on my part.

Thank you in advance for your help,

Jason Hemann

That's pretty old.  Try the HEAD version from gitlab.

(I'm working on getting a 3.1 release out.  A few minor things to do,
mainly documentation, but no promises when it will get done.)

Per,

Ah. I'd grabbed the version from homebrew. I'll go grab HEAD, and report
back if there are more problems.

Thank you,
