Rename Fortran requirement to fix option generation So, `depends_on :fortran => :optional` will generate "--with-fortran" rather than "--with-fortranRequired". 2013-06-25 21:08:59 -05:00			`class FortranDependency < Requirement`
Add :fortran requirement 2013-06-23 18:35:20 -07:00			`fatal true`

fortran_dependency: use gcc instead of gfortran. 2014-05-15 21:03:12 +01:00			`default_formula 'gcc'`
