 OpenAxiom currenly requires a Lisp system for its runtime support.
 OpenAxiom is known to build with the GNU Common Lisp (GCL versions 2.6.7
 or 2.6.8), Steel Bank Common Lisp (SBCL version 1.0.22 or higher,
-except 1.0.29), CLisp (version 2.44.x or higher), and ECL (version

 higher than 11.1.1), Clozure CL (version 1.3 or higher).  So, if you
 already have any of the above mentioned Lisp systems, your are good to
 go.  Otherwise, you would need to install any of the Lisp environment

 Ah, one more note:  OpenAxiom requires GNU Make.
