I attempted to upgrade my Sage software from 2.something to 3.0.
I renamed my old /Applications/sage folder, copied in the new one from
the dmg,
and did the usual launch of the sage icon using Terminal.
It said

----------------------------------------------------------------------
| SAGE Version 3.0, Release Date: 2008-04-21                         |
| Type notebook() for the GUI, and license() for information.        |

The SAGE install tree may have moved.
Regenerating Python.pyo and .pyc files that hardcode the install PATH
(please wait at most a few minutes)...
Please do not interrupt this.

You can find it at:

Gary's readline needs the ctypes module, from:

(Note that ctypes is already part of Python versions 2.5 and newer).

Defaulting color scheme to 'NoColor'

I captured all of the output (about 90 lines or so) into a text file
and I can provide it upon request.

Any clues?  How should I proceed?
