I installed the sagemath software on an Ubuntu machine and nothing executes. I type

sage: notebook()
NameError: name 'notebook' is not defined


sage: 2+3

NameError                                 Traceback (most recent call last)

/home/myusername/Downloads/sage-4.7-linux-32bit-ubuntu_10.04_lts-i686-Linux/local/bin/<ipython console> in <module>()

NameError: name 'Integer' is not defined

On opening sage I get the following message. I just installed sage and I have no idea what this means or how to correct it.

It looks like you haven't got gfortran installed; see this sage-support thread.

See also the earlier question here.
