libgfortran casero

Mi aplicación Python utiliza scipy, que aparentemente necesita libgfortran. Después de una reciente actualización de brew, mi aplicación de Python no se ejecuta debido a un problema de dependencia de libgfortran:

dlopen(<snip>/scipy-0.14.0-py2.7-macosx-10.10-intel.egg/scipy/linalg/_fblas.so, 2): Library not loaded: /usr/local/lib/gcc/4.9/libgfortran.3.dylib

Tengo instalado gcc 4.9, pero no hay ninguna biblioteca fortran ni nada que coincida con /usr/local/lib/gcc/4.9/ fuerte . Hay toneladas de otras librerías en /usr/local/lib/gcc/4.9/

He instalado con éxito gcc 4.9 a través de homebrew, sin embargo no he podido conseguir instalar gfortran:

  ~  brew install gfortran
Error: No available formula for gfortran
