Currently the gfortran compiler provided by this brew is only supported
for:
- XCode 3.1.4 on OS X 10.5.x
- XCode 3.2.2/3.2.3 -- 4.0 on OS X 10.6.x
- XCode 4.1/4.2 on OS X 10.7.x
The AppStore and Software Update can help upgrade your copy of XCode.
The latest version of XCode is also available from:

def caveats; <<-EOS.undent
Brews that require a Fortran compiler should not use:
depends_on 'gfortran'
The preferred method of declaring Fortran support is to use:
def install
...
ENV.fortran
...
end
