--------------------------+----------------------------
If you install Sage system-wide (e.g., in /usr/local) for all users on
your system, most of the pexpect interfaces will be completely massively
broken. The bug is big, but the fix is pretty trivial:

The problem is that elsewhere in the code there is an
