This is on an ubuntu system which never failed to build sage before.
Ticket #7485 [1] removes the Linux Fortran binaries from the Fortran
spkg. Before Sage 4.3.1, Fortran wasn't a pre-requisite for building
Sage. However, as of Sage 4.3.1, Fortran is now a pre-requisite. See
ticket #7484 [2] for updating the README.txt to reflect this new
pre-requisite.

Though it would appear the log posted by Dan
http://sporadic.stanford.edu/bump/sage-4.3.1-errors
shows the compiler was configured with Fortran support:
Configured with: ../src/configure -v
--enable-languages=c,c++,fortran,objc,obj-c++,treelang --prefix=/usr
--enable-shared --with-system-zlib --libexecdir=/usr/lib
--without-included-gettext --enable-threads=posix --enable-nls
--with-gxx-include-dir=/usr/include/c++/4.2 --program-suffix=-4.2
--enable-clocale=gnu --enable-libstdcxx-debug --enable-objc-gc --enable-mpfr
--enable-targets=all --enable-checking=release --build=i486-linux-gnu
--host=i486-linux-gnu --target=i486-linux-gnu
I would suggest that 'prereq' is updated to check for Fortran on all platforms
except OS X. I have created a ticket for this.
http://trac.sagemath.org/sage_trac/ticket/8024
and will do that.
I think this is one further example of the point I made less than an hour ago.
The removal of the Fortran package was made in sage-4.3.1.rc2, which very
quickly becomes 4.3.1, with insufficient time given for testing before making
the 4.3.1 release.
