doctest failure in sage/sage/groups/perm_gps/cubegroup.py due to upgrade to Maxima 5.19.1

[sagetrac-drkirkby]

On Solaris 10 update 7 (SPARC), the following tests failed. Both ECL and Maxima were updated - ECL version 9.8.4 (see trac #6564); Maxima version 5.19.1 (see trac #6699). Updated spkgs can be found here.

The Rubik's cube solver (I think) calls a C program. Can it be tested if that C program is compiled correctly?

But honestly, I don't know what this failure means. I think Robert Bradshaw needs to look at it.
