WARNING: the environment variables SAGE_FORTRAN and SAGE_FORTRAN_LIB
are deprecated since sage-5.3.
The GNU Compiler Collection (GCC) is included in Sage and will be
installed if you do not have a Fortran compiler. If you do have a
Fortran compiler installed and you want to specify its path, you can
use the standard environment variable FC (instead of SAGE_FORTRAN) to
point to the Fortran compiler.
As replacement to SAGE_FORTRAN_LIB, you can either add the directory
containing the Fortran library to LIBRARY_PATH and/or LD_LIBRARY_PATH,
or copy/symlink the Fortran library into \$SAGE_ROOT/local/lib. In most
cases, none of this is needed as the compiler/linker should find the
Fortran library by itself.
Support for SAGE_FORTRAN and SAGE_FORTRAN_LIB might be removed from
future versions of Sage. Moreover, these variables are not tested
anymore and might not work as you expect.
