I'm not quite sure which installation of Python I should try, so I've
tried all Python installations on the above Linux machine that I was
able to find. Here are the results I received:
[1] The system wide Python installation is 2.4.2 and, not
surprisingly, I was able to do "import math" from within the Python
session.
[2] My local Python installation on that machine is 2.6.1. The same
story as above.
[3] The same story as above for Python 2.5.2 that's packaged with Sage
3.2.3. That is, I did "import math" after running
SAGE_ROOT/local/bin/python, and tried again with "sage -python".
I couldn't load sage, as the error message below indicates that
ipython hasn't been built yet:
