For kicks I decided to give -fortran a try. I find it interesting that with Fortran installed using either the fortran flag in package.use, or just not setting the flag at all, I apparently do not need the c++ libraries that I do need when I choose -fortran. However it seems that -fortran doesn't eliminate the need for installing a Fortran compiler. It simply shifted it from the GNU gcc Fortran package to the Intel Fortran Compiler (dev-lang/ifc)c2stable ~ # emerge -pvDuN @world These are the packages that would be merged, in order: Calculating dependencies... done!

I emerge -C ifc and revdep-rebuild rebuilt some stuff but it is gone now. So, you may have to work with it but it *might* be removable too.
