As of Sage 4.3.1, gfortran is a pre-requisite [1] for compiling Sage
on Linux. I have updated the above URL to include instructions for
installing gfortran on Debian/Ubuntu.

The Installation Guide needs some updates to account for the changes
at ticket #7485 [1]. This issue is tracked at ticket #8080 [2]. A
similar issue is also tracked at ticket #7484 [3], but for the
README.txt at the top-level Sage directory.

The instructions at that URL is for Sage version earlier than 4.3.1,
so they may not work for Sage 4.3.1 due to ticket #7485. See the URL

http://www.sagemath.org/download-source.html

for updated instructions for Debian/Ubuntu.

It's recommended that you have Fortran installed. On Debian/Ubuntu, if
you have gfortran installed, the command "which gfortran" should
report the location of that Fortran compiler:

[mv...@sage ~]$ which gfortran
/usr/bin/gfortran
[mv...@sage ~]$ gfortran --version

If you don't have gfortran on your system, but you have sudo
privileges on your system, you could install gfortran as follows:

sudo apt-get install gfortran
