Thanks, I forgot about that way to do it. The lack of readline makes
it rather unfriendly though. I am just a beginner with lisp myself.

Using 4.0 and 4.0.1 I get a long traceback that ends with:
RuntimeError: Unable to start Lisp because the command 'clisp-
noreadline --silent -on-error abort' failed.

Sage was compiled from source on Scientific Linux 5.1. I don't have a
global clisp available though.
I figured that it was something that had just not been looked at yet
in the transition to ecl.
