Great, thanks. It seems that without hints to do otherwise, the
configure script uses clisp as the lisp implementation. I note that in
README.lisps, we have the following:

Maxima devs: Is there a good reason to use Clisp as the default on Linux
boxes? Maybe we could switch to GCL or SBCL (I'd prefer the latter)
