 maxima merely requires an ANSI Common Lisp, not necessarily sbcl.

 If you can run an openjdk, one could use the +abcl variant to install
 maxima.

 {{{
 port install maxima +abcl
 }}}

 sbcl itself can be built via abcl on those platforms where no bootstrap
 sbcl image is available.  Such machinery was once part of the sbcl
 Portfile but seems to have been removed.  I will take a stab at improving
 the sbcl Portfile's use of universal architecture as this issue.

 It would be nice to encode these possibilities in the maxima ports use of
 the universal architecture as well.

 It would be good for SBCL to be able to state somehow that it doesn't run
 universally.  What is the best way to do this?

 I have some reading to do about what universal currently entails.
