Does dbl need gcl, does other lisp work, and a possible bug

Hi,

        Is dbl supposed to work with clisp or anything other than gcl?
I saw a message from the mailing list archive by the late
William Schelter that suggests it should, but when I tried to
load dbl.el into emacs it just complains that it could not load
gcl.

	On a related note, can I compile maxima with any lisp other 
the 3 given in the README.lisp, such as open mcl, or SBCL, with the push
of a button?  What is exactly special about gcl, cmucl, and clisp
that they work with maxima, or should I phrase the question the other
way around?

	 notice that ctrl-Z, instead of suspending maxima and return to 
the shell, put it in semi-coma, which is revived by a CONT signal send by 
kill to the lisp interpreter.  I thought this might be a maxima problem 
because ctrl-Z does suspend the lisp interpreter when I am running it alone.
I am running clisp 2.7 under darwin.

Ok, thanks

Zheng
