Does not seem to build with homebrew version of gfortran on OSX

With array fire installed to the default **/usr/local** directory, and this being correctly set in common.mk, this fails with the following error: **gfortran: error trying to exec 'cc1plus': execvp: No such file or directory**

When using gcc instead (changing @gfortran to gcc in the makefile), I get the following errors:

Comienza con common.mk y el makefile, y luego reproduce la compilación de Homebrew gfortran en macOS usando la instalación predeterminada en /usr/local. Inspecciona el fallo de cc1plus y los símbolos no definidos indicados; se considera terminado cuando el wrapper de Fortran se compile y se enlace correctamente con la configuración documentada.
