 Replying to [comment:10 dyne2meter]:
 > […] I don't want to try to convince maxima's port maintainer to switch
 the LISP system to ecl, which builds on my system without issues. I don't
 really know where to go from here, so somebody with more knowledge of the
 ports build system is going to have to step in. Why do I mention ecl?
 SageMath uses ecl to support maxima in their system and my build of
 SageMath from its makefile goes off without a hitch, even with the most
 current version. I can use Maxima in SageMath, but I am pushing this here
 on principle because I don't like to see my system progressively obsoleted
 deeper and deeper by stuff Apple is doing as a corporation. That said, I
 am perfectly  happy to be told by the maintainer for this port that we
 have reached a dead end or that it's too much trouble to look farther.

 Note that the lang/maxima contains a variant to use 'abcl' or 'clisp' both
 of which Maxima just fine.  I'm pretty sure that the Maxima maintainer
 would be willing to add a variant for 'ecl' as well as opposed to moving
 the default off of 'sbcl'.

 I'm not quite ready to declare 10.11 dead for sbcl.  But I continue to not
 have a way to build/develop/test patches for that platform.
