Thanks, Gabor. I have followed the instructions given at:

http://groups.google.com/group/comp.os.linux.networking/msg/656bbead5059fc07

as suggested at

http://code.google.com/p/ryacas/

However, I still get the following:

$ telnet localhost 9734
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection refused
telnet: Unable to connect to remote host: Connection refused
$
