From another fourm, Computing.net, I was able to get an anwer on how to get teh ICA client to work on Knoppix.

The following tidbit was supplied by "3Dave"

Download and install libxaw6. You are probably best off using apt-get to install it, failing that this link might help:
http://packages.debian.org/stable/libs/libxaw6

You might already have v7....if so I think you want to force the install


I followed these instructions and it worked.
