Subject: Error when starting KaShell language
To: kawa@sourceware.org
Content-Type: text/plain; charset="UTF-8"

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,
