client error on startup

Hi, Generally Hobbit is running very well for me. I really appreciate all the work everyone has done to make it so useful. Problem with a client. I scp'd the client directory from the hobbit server to my client machines. This has usually worked well except when I did the same thing to a redhat 4.2 server.

The error I get running ./runclient.sh start is; line 83: /home/hobbit/client/bin/hobbitlaunch : cannot execute binary file.

The privileges are good, everything else looks the same as other machines.

i also see the error ins log/messages ; modprobe: can't locate module binfmt-464c.

Do I have to rebuild the client on this particular server? Is there a separate tar file for clients or do I have to install the complete Hobbit tar file?

Thanks.
