You have no programs, that *need* fortran, but it could well be, that you have programs installed, that perform better when compiled with a fortran compiler. I think of sci-libs/fftw here as an example. It's used by programs like blender, imagemagick and maybe some others. The developers of said library use fortran, because they benchmarked it. If you disable fortran, you use the slower C fallback solution. If you disable fftw in those packages, you get a slower implementation too afaik. After all, gentoo is a source based distribution. We all already have a couple of languages installed. There's a C compiler a standard user will never use. There's a C++ compiler only used by programmers. We all have them, only to compile programs, that need them. Why not enable fortran, even if it's only optional, to get the best of the available implementations? In the end it's only one programming language more installed on your system. Regards, Michael
