10 For kicks I decided to give -fortran a try. I find it interesting that
11 with Fortran installed using either the fortran flag in package.use,
12 or just not setting the flag at all, I apparently do not need the c++
13 libraries that I do need when I choose -fortran. However it seems that
14 -fortran doesn't eliminate the need for installing a Fortran compiler.
15 It simply shifted it from the GNU gcc Fortran package to the Intel
16 Fortran Compiler (dev-lang/ifc)

67 In my case I'm sticking with the gcc fortran package as it's the devil I know...
