Ok, I built scilab-4.1.1 on Fedora 13 (with no problems :-).
The scilab.el mode of Emacs-23  behaves the same way.

I suspect the reason is buried somewhare in the following messages.  (I
byte-compiled the scilab.el w/in emacs-23 and it successfully completed,
but with this pile of warnings.)

I do hope someone w/in the Scilab community who knows how to program
in e-lisp and would be willing to get this valuable mode working again
will see if it is fixable.  I, personally, live in Emacs 98% of the time
and to _not_ be able to use Scilab in that mode is already VERY painful!

In case it helps: the mode seems to work for editing.  Key binding work
and the few editing functions I tried work.  It is just the scilab-shell
that hangs.  The run buffer get created but scilab never starts.

Regards,
Dean
