Something else looks wrong, i.e the string "3.2.1.rc0" should not
appear in the backtrace at all. There can be numerous issues like a
bungled SAGE_ROOT setting at some point that is now causing trouble.
Does maxima from that install work via "sage -maxima"? Just because
the doctest claims that is doesn't start does not mean that it doesn't
work in general. I would also check the repos for unresolved merges,
multiple heads and so on. Some environment variable can also play a
role here. Since linking the sage script just works I would always
recommend linking it into $PATH somewhere under a different name
instead of setting $SAGE_ROOT manually as recommended in the
documentation since it is too easy to scrw that up. The checking code
if SAGE_ROOT is overwritten also makes it too still possible to shoot
yourself in the foot.

Ok. I would suggest to rerun the failed tests with -long to see what
happens. If the CPU usage stays near 0 it is a synchronization /
maxima issue, but the timeout will be raised after 30 minutes.
