I have other ways but if it mostly work and the notebook also works
we may want to upgrade that antiquity like there is no tomorrow.

Maybe this patch solves the problem:

https://github.com/pexpect/pexpect/pull/109/files

I pulled pexpect 3.x from github which as I understand it is quite a
few patches ahead of 3.3.

$ git clone https://github.com/pexpect/pexpect.git
$ cd pexpect
$ git checkout 3.x

then installed it into my sage 6.6 the hard way (maybe there is an easier way?)

$ $HOME/sage/sage -python setup.py install --prefix $HOME/sage/local
$ rm /home/wspage/sage/local/lib/python2.7/site-packages/pexpect.*
$ rm 
/home/wspage/sage/local/lib/python2.7/site-packages/pexpect-2.0-py2.7.egg-info

and rebuilt the sage library

$ cd $HOME/sage
$ ./sage -b

Now I get only one failure in

$ ./sage -t --long src/sage/interfaces/expect.py

this particular failure is all over the place with pexpect 3.3 so there is
something that is in need of updating on expect.py side before going ahead.

Is there a possibility of creating an experimental package to install
pexpect 3.3 ?

I see references to "doctests failing" but no details.  It would be
good to make this easier to test.

After reading the docs:

http://pexpect.readthedocs.org/en/latest/index.html

It seems that version 3 and later are supposed to handler unicode
properly.  Version 3.3 requires Python 2.6 or later.  Since Sage is
already at Python 2.7 is there a good reason why Sage is still using
an older version of pexpect?
