I've found the source of the bug:

Up to version 5.17.1, Maxima's "server" used to be called with a
command:
   maxima -r ":lisp (start-server 4008)"
but since a couple of months ago it is now been called with:
   maxima -r ":lisp (start-client 4008)"

When you call the latest version, it works with "start-client" but when
you attempt to call a previous version the same command "start-client"
fails.
That will be easy to fix: I'll do it over the weekend.

If you want, you can do a quick fix yourself:

Copy /usr/local/bin/xmaxima to another file such
as /usr/local/bin/xmaxima-old

Then edit that file (it is a plain text script) and replace the two
places where start-client occurs by start-server
You can then use "/usr/local/bin/xmaxima-old -u 5.17.1" to start that
version, or older ones, and: "/usr/local/bin/xmaxima" to start the
latest version.

Thank you very much for reporting this bug!

I'd be interested to receive any feedback from your comparison between
wxmaxima and xmaxima so I can try to improve xmaxima.

Regards,
Jaime
