install f2c resolve problem, so i think it's only a depend problem. sorry for my english.
Indeed that's a bug. It appears to not be specific to f2c, but more along the lines of lacking ANY sort of fortran compiler.
Ok, let me try confirming this again...
Confirmed by Chris White.
This might need to be changed to LATER, as there is a discussion on how to integrate fortran compilers into the ebuild. Since there are many fortran compilers avaliable, it needs much more effort than a simple one line ebuild fix. The devs are working on it right now, but hopefully the sci heard can provide a solution for now.
I guess this is outdated.
